    Chiyawa got a reaction from FRD in Price drop of SSD, is it just in Malaysia or world wide?   
    I see.
    The price I observed is still pretty high but had a little drop just this week, so I'm curious if this is the case for world wide. Thanks for the info.

    Well, I spotted today on Shopee. It seems there are slight price cut.
    WD Black SN750 500GB M2 NVMe SSD with heat sink sell over RM500 last week (I think RM479 is probably the lowest when they are on sale). Today, they are selling RM437.
    WD Green 480GB 2.5 inch SATA SSD usually sell at about RM275 or close to RM300, but it was drop to RM262
    AData Swordfish 500GB M2 NVMe SSD usually sells over RM300. Today I noticed it drop to RM280.
    Kingston A400 480GB 2.5 inch SSD sells for RM252.60
    Viewnet price list (19th July 2021) also show significant price drop on some SSD (Mostly SATA SSD). For example: Kingston A400 480GB 2.5 inch SSD selling at RM239 (I remember last week when I check they are selling RM279).

    Chiyawa got a reaction from Constellation in How much is too hot for a pretty old GPU?   
    Well, try using some monitoring software like MSI Afterburner to test if your GPU thermal throttled in any way during gaming or stress test. In a general rule of thumb, The max temperature for a GPU is about 95c. Some would have 105c before the GPU cut itself off.
    Radeon HD8490 won't produce a lot of heat, so you don't really need to worry about thermals. What you really need to worry is dust on the heat sink and fans. Having it clean regularly should make it perform optimally.

    Chiyawa got a reaction from Nanook in Will this Case Fit a 38mm Thick Rad Top Mount?   
    Scroll down a bit until you see the specification. It listed the top radiator clearance is 65mm.
    Generally, in most modern case, if you see a large gap between the the motherboard I/O cut out and the top of the case, the case will likely to have 55mm-65mm clearance for radiator and fan, and can fit most standard AIO coolers.

    However, you should always check the manufacturer website for more information of the case, radiator clearance, fan support and other important information.

    Chiyawa got a reaction from AnirbanG007 in Logitech F310 Gamepad Compatibility for Retro Gaming   
    Ah. Well, actually, after using XBox Series X/S controller, it is probably way better than than F310. My F310 died (the dongle, not the gamepad) and now it is a glorified paper weight. Also, after close to 2 years of usage, the rubber became sticky. Rumble (or vibration) is weak. LT and RT are very stiff. Too bad your budget is restricting you, otherwise I would strongly recommend the XBox Series X/S controller.
    XBox can use Bluetooth, the dedicated wireless dongle, or cable, means that if one is not really working, you can use other method. I actually use it in many devices including smart phone and laptops through Bluetooth (I have to re-pair them if I switch devices). As for desktop, I used cable (cheap USB-C to USB-A cable that support USB 2.0 interface will work).

    Chiyawa got a reaction from TheCoder2019 in Does PC Building Simulator shows accurate result?   
    So, first of all, I have virtually no experience in water cooling, I just know they can help cool the component. I do study a lot from the Internet but I have no experience in real world situation.
    Just recently, I purchased PC Building Simulator game from Steam, and I'm having a blast. Still, I'm not sure if this game provide an accurate simulation when it comes to water cooling and fan cooling (because I can actually build a PC without any case fan, and the thing didn't even overheat when stress test it with 3D Mark). Can anyone clarify this?
    Also, I wonder if you need to level up to unlock more parts to play around in free build, because I certainly didn't see much ThermalTake Water Cooling components. ThermalTake used to be one of the early pioneer of water cooling PC.
    By the way, I know this is a silly question, but in real life, if we plug the CPU to a 120mm rad then to GPU and then to 360mm rad and then back to reservoir and pump combo, will the GPU run cool? Assuming I use Ryzen 9 5950X and Radeon 6900XT. Each fan provide about 1.2mmH2O and 45CFM and 120mm radiator has one fan installed and 360mm radiator has 3 fans installed.

    Chiyawa got a reaction from tgp1994 in Am I out of date? :(   
    It should help you, but only a bit. I'm suspecting that the mounting pressure of your heat sink to your gpu is loose, so maybe try to tightened it a bit might help.
    Also, check your exhaust fin. I know many people didn't think that the 'sponge' inside the fan covering the fins as dust, for they thought it is a filter of some sort. You need to tear down the fan to get rid of it.
    Or it could be what @genexis_xsaid, the thermal design of this model is not great and couldn't cool off adequately, resulting in thermal throttling.

    Chiyawa got a reaction from LogicalDrm in I need help with OBS studio   
    I think this could be because your video captured device couldn't get the resolution right.
    To determine if your video capturing device captured the image correctly, you can use the Windows 10 in-built Camera app to determine (note: you might need to close OBS and other software that uses the device). You can then play the settings from your PS3 to see if the resolution ratio can be detected correctly.
    This is purely depends on your devices, so you may need to look up to the device manual if they have some settings need to be set. Sometimes, unplugging and re-plugging the device might help.

    Chiyawa reacted to Nystemy in How Power Supplies Work - Turbo Nerd Edition   
    As an electrical engineer myself, videos like these sometimes makes me cringe. Or most times makes me cringe to be fair...
    There is the small niggles like "Switch-ing mode power supply" being technically incorrect, since the technical term is just "Switch mode power supply" or SMPS for short, and Varistor aren't called "VerY-resistors". And the primary side mosfets don't actually make a square wave, it is more a saw tooth to be fair. (Not that the mosfets even generates it, it is more a side effect of flyback converters.)
    But I will be honest and say that this video is honestly well made.
    And isn't full of actually incorrect and misleading information. A rare feat outside of electrical engineering channels. (considering how even such channels at times gets important details wrong as well.)
    Though, could have explained flyback converters to be fair, they are actually rather trivial in practice.
    Since all they do is let current flow through the primary side, this induces magnetic buildup in the core, that induces a reverse voltage on the primary side, trying to prevent an increase in current flow. On the secondary side it also induces a reverse voltage that is blocked by our rectifier.
    When our mains side transistor turns off. Current suddenly stops flowing on the primary side, the magnetic field in the core collapses, inducing a forward voltage in both the primary and secondary side. Our primary side won't create any noticeable current since out main switching transistor is off and won't let it pass. Our secondary side however happily lets current flow through the rectifier in the correct direction.
    Then we just regulate how much power we send over by how long we keep our main side transistor on for each cycle. We can also reduce the frequency, but that limits our ability to recapture the energy in the transistor gate itself, ie our switching losses gets higher.
    And a fun side effect of flyback conversion is its ability to generate any arbitrary output voltage regardless of input voltage. The transformer can on paper have a 1:1 turn ratio and still do 400 V to 12 V conversion just fine. But in practice, this would require us to have a rectifier able to handle a 412 V reverse bias at the minimum, not accounting for switching noise. (something that is really common in these supplies.) 412 volts isn't much, there is 1000 V rated diodes on the market, but typically the secondary side will use synchronous rectification using FETs, since this results in less power loss, and high current transistors typically don't also do high voltage, unless it is physically huge and typically water cooled.
    Also a quick note on capacitors.
    It is actually very hard to just make a list of capacitors and say, "These brands are good." Because each brand have different types of capacitors with different ratings, aiming at different applications. Where the ratings are more than just capacitance, voltage, ESR, MTBF @ temp. There is additional specifications that are harder to see at the surface. Like recommended peak and ripple currents at a given temp, and the ESR over frequency since it varies, not to mention the obvious package/formfactor/footprint it is built to. Then there is safety features like how it vents, if it has internal inrush limiting, among other details.

    Just looking at the brand is a bit short sighted to be fair. But a Nippon Chemicon is generally of better specs than a Rubycon, but they are both good capacitors. The important part is that they actually live up to their specs, and some of the really "scummy" "brands" will actually rip off name brands and not deliver even close to what is stated on the tin.... And this is the kind of crap one should avoid.
    Though, I don't know how many times I have talked to people/customers and heard the statement, "why is there so many different but similar parts, can't the industry just make 1 component of the type to fit all applications?!", and the answer is that it isn't that simple. It might though seem silly how there is about a 1000 different 1µF electrolytic capacitors on the market, but they have different voltage ratings, ESR, packaging, and MTBF values, and construction techniques, so they aren't even close to interchangeable. And that is just 1µF electrolytic caps, then there is different values and dielectrics, and then all the other component categories like resistors, inductors, transistors, diodes, LEDs, IC, terminals/contacts, buttons, etc...

    Chiyawa got a reaction from leclod in Anyway to upgrade your laptop RAM that is soldered to the motherboard?   
    I see.
    For many thin and light 13 inch laptop, they no longer offer a RAM slot. All RAM are soldered. I just recently bought Lenovo Yoga 6 13ARE05, and all the RAM are soldered. I got a 16GB, but I believe the CPU can support up to 32GB, but Lenovo didn't offer it. I do run some VM, so RAM is a concern. The Ryzen 7 4700U has enough juice for VM, but the RAM is a little bit limited.
    Agree. But I think manufacturer should make this available. I have a Surface Pro 4 with 4GB RAM, and now it is technically an e-waste because I couldn't run a lot of application (GIMP always crash). It is now sitting there collecting dust. Well, at least it is still good for watching Youtube and working with Office apps.
    Not to mention the correct RAM. I found that many RAM chips has different pin layout too. Still, manufacturer should standardised the connection for upgrades.

    Chiyawa got a reaction from Mark Kaine in Really weird thing just happened…   
    Definitely. If you stay in country with 240V, you'll notice that when the power grid faces a brown out (a sudden drop of voltage), the PC PSU can still run because it can, in certain cases, run at 90V AC (Although 12V rail may saw a great dip of voltage).
    Also, larger wattage PSU has more capacitor to stored its charge.

    Chiyawa got a reaction from Yontsalot in Slower drive speed with 2M USB 3.0 extension cable.   
    Depends on the quality of the cable, you may face a drop of performance if the cable length is long.
    Generally, I would steer clear long cables or extension cables, because they are quite unreliable and produce lots of interference that results in low performance. I do have a USB 3.0 extension cable that perform slower than USB 2.0 extension cable of the same length.
    So, well, you might need to get a good quality cable (the blue colour generic USB 3.0 extension cable is made of poor quality material and cheap insulators).

    Chiyawa got a reaction from RAGNES7 in Does it matter which slot I put my GPU in?   
    For AMD system, you would want to attach your graphic card to the nearest PCIe X16 slot to the processor. This is because that PCIe slot connected to the processor directly reduce latency by a little.

    Chiyawa got a reaction from voltageconfusion in Will the laptops, monitors & tvs sold in the USA (120v/60hz) work in a country that uses 230v/50hz?   
    Depends on the adapters. If the adapters does stated that AC input is 100v to 240v and frequency input is 50Hz/60Hz, yeah, it should be capable of adapting almost all AC electrical standards of the world (for consumers, at least).
    Please study the adapters voltage carefully. And you 'may' also need to buy a new power cord just to be safe (the fuse may blow up if the voltage and current is over the rated voltage and current).

    Chiyawa got a reaction from zogthegreat in Looking for fan recommendations for Hyper 212 CPU cooler   
    Well, I did switch out my fan to CoolerMaster Masterfan R120 A.RGB fan. The reason I switch into this is because they have good static pressure (2.14mmH2O) and decent airflow (59CFM), and they run silent even at 2000rpm (31dBA, may still be loud to some people, but once the fan is inside the case, it's barely audible). You can check the specs here: https://www.coolermaster.com/catalog/coolers/case-fan/masterfan-mf120r-argb/#specifications
    I install 2 fans and make them run at 100% in push pull config and exhaust the air to the rear. My PC case is ThermalTake Versa H26 and I installed 2 fans at the front case as intake, 3 at the top of the case as intake, and 1 at the rear as exhaust, all using ThermalTake Pure Plus 12 RGB radiator fans and all run 100% (even if it says radiator, it only has static pressure of 1.59mmH2O, but the airflow is good at 56.45CFM running at 1600rpm. Link: https://www.thermaltake.com/pure-plus-12-rgb-radiator-fan-tt-premium-edition-3-fan-pack.html) I run a stress test and the CPU (Ryzen 5 3600) using Cinebench, full load. The CPU run at 4.2GHz all cores for about 3 and a half minute before gradually reduce its speed as its temperature gradually reaches 70c. The temperature stays at 72c with all cores running 3.9GHz constantly even after 1 hour of stress test. My average room temperature is around 34c (living in tropical area).
    Anyway, here's something you can try:
    - If there is an empty fan bracket, install another fan and make them push pull the air through your heat sink. I find having 2 fans in push pull configuration helps the temperature a bit.
    - Increase your fan speed. I just put my fan to run 100% all the time. My idle temperature stays near room temperature (about 38c in 34c room)
    - Your case may choke with stale air. Increase air intake by increasing fan speed to all your front fans and reduce exhaust by reducing fan speed to your rear fan and top fans (assuming your top fan was set to exhaust).
    - If your CPU cooler exhaust the air to the rear, set your top fans as intake. This will bring in more fresh air to the cooler.
    Hope my experience helps you a little.
