    Hardline bending kit

    If we're talking about acrylic/PETG, I would say freehand is perfectly sufficient for most people, you only need a saw and a silicone insert (which is pretty much tube specific anyway and so should be bought).
  2. Agreed, consider allocating the budget towards platform/cpu upgrade instead, would get you actual improvements. If doing it just for looks, then I suppose its okay, that's up to you.

    When do you need a second D5 pump?

    Generally speaking, almost never. Yours for example is completely fine for a long time. Personally i think its more for redundancy on machines that have a long up time. My 4 GPU + 2990WX workstation with 1200 mm worth of radiator space has 2 D5s but i think for flow alone, one might still have been okay, but as this machine is on almost 24/7 a bit of redundancy makes me sleep easier at night.
  4. So the time for the annual maintenance of my Define C was upcoming. So i decided to take the opportunity and upgrade my case to a meshify C since a TG upgrade didnt look like it was coming anytome soon for the Define C. Below is whay my previous systrm looked like (almost 1 year ago) and it has served me well although with a few things that i wasnt happy about. Old Build Wonky bends in a few places Uneccesary fittings here and there Lack of a rear fan janky reservoir mounting solution Soi have been working on ironing these issues out and thought maybe some would be interested in the journey too.
  5. Meshify C and Define C both have filters for the top.

    D5 Thermal pad

    The D5 is cooled by the liquid flowing through it and so does not need a thermal or heatsink under it.

    Case will support a 140mm fan but not Rad?

    Also, thickness is a major consideration. Most radiators are 30 mm when thin and that is already 5 mm thicker than a fan. Furthermore you would need to attach a fan onto that so then you are easily into the 55 mm ish thickness. At this thickness you might start interfering with motherboard components such as VRM heatsinks and/or RAM sticks. If you say which case, motherboard, cpu cooler, and RAM, we may be able to give more targeted advice.

    Have you tried underclocking the gpu core and memory?

    Custom Loop - Mod AIO Cooler

    Or be like op and assume it isnt mixed
  10. Hiya, Ive done my loop in both the Define C and the Meshify C. Counter intuitively the Meshify C is both quieter and cooler with my loop. You must remember that more airflow = cooler which means you can slow your fans down to maintain the same temperature. I also found that with the C series, since the space inside the case is so limited once you have 2 gpus, 240 mm radiator and a 360 mm radiator, exhausting the heat from the radiators is actually very beneficial since using a big 360 mm as an intake was reheating the case internals especially at low rpms. Having all radiators on exhaust and using the rear fan as an intake dropped my fluid temperatures close to 10 degrees.

    Custom Loop - Mod AIO Cooler

    AIOs are almost always mixed metals (exceptions are like EK Predator, Alphacool Eisbaer, the old Fractal Design ones). Its a cost saving feature and manufacturers expect people either not to notice or care. The micro channels that the fluid passes over is copper.
  12. I use bitspower blocks for my 1080 turbo.
  13. I didn't read everything, but a T-splitter and a ball valve between B-C or A-C should be just fine. I wouldn't have any long tubes coming off the splitter though, just buy a soft tubing and a fitting that you can screw into when needed. You might need an angled fitting if it's extra tight. See below in my Ncase M1 log.

    After Watercooling, Would You Do it Again?

    For me, its the noise reduction of a correctly configured loop. I must always have at least 2 GPUs (and ideally more) for my use case and so the sound output is no joke if left on air. Water lets me run calculations and also still have a conversation in the room. So yes, I would do it again, and have so done it time and time again.

    It's that time again to upgrade our office workstations! For Science! We have been having a great experience using these quad-GPU machines + Threadripper for our scientific calculations (structural biology, for those curious). It is of course very rare to see quad-GPU machines for gaming nowadays so I thought it is good for some documentation for those crazy enough to stumble across these kind of ideas. We have to use NVIDIA cards since our programs are only CUDA compatible, and we can't use Tensor cores, RT cores, or double precision, and so the GeForce GTX series are still the most ideal. We also have a relatively steep memory capacity requirement and so need at least 11 GB VRAM - this favors 1080 Tis over 2080's. Since the release of the second generation Threadripper, we wanted to roll out these quad-GPU machines further in our group but also try to make some improvements. Mainly in the department of GPU thermals and as a byproduct, noise (custom watercooling all the machines would be ideal, but is not an option for now). Before rolling out on a massive purchase, we first assembled one machine as a proof of principle using the specs below. Notably we use a riser cable to bring the 2nd GPU out into the vertical slot of the View 37, this means that only 1 graphics card is choked as opposed to 3 cards being choked in a standard layout. Also, we opted for a QVL certified kit of memory since getting 128 GB of memory to work on the first generation was a bit of a nightmare that I didn't want to re-live. Going to the View 37 Case also reduced the footprint of our workstation from the cube that is the 740D while also allowing for the vertical GPU mount that helps in thermals (and noise) in this very peculiar scenario. Assembled Prototype: CPU: AMD Ryzen Threadripper 2990WX Motherboard: ASRock Fatal1ty X399 Professional Gaming Memory: G. SKILL Flare X (for AMD) F4-2400C15Q2-128GFX (128 GB, 2400 MHz, CL15) CPU Cooling: Noctua NH-U14S TR4 SP3 in Push-Pull GPU: Gigabyte GeForce GTX 1080 Ti Turbo 11G in Quad Layout PSU: Corsair AX1600i Case: Thermaltake View 37 Riiing Edition Fans: Fractal Design Venturi HP-14 PWM 140 mm Extra: Thermaltake TT Premium PCI-E 3.0 Extender 300 mm Storage: 500 GB + 1 TB SATA SSD I was largely pleased with this build and decided to proceed with the other builds with some minor adjustments. Getting hold of 1080Tis are getting more difficult for everybody, and so we'll see what we end up with. CPU cooler wise, I could obtain the Dark Rock Pro TR4 for a similar price, and so went with them since the performance is similar while subjectively is more appealing to the eye. Finalized Specs (build in progress....): CPU: AMD Ryzen Threadripper 2950X (mostly) or 2990WX Motherboard: ASRock Fatal1ty X399 Professional Gaming Memory: G.

    I should have some updates soon, we had some definite hiccups with regards to obtaining GPUs. There are BIOS options to turn off the LEDs (although there aren't too many to begin with). I do indeed wish there was a second vertical mount, currently the GPU on the vertical mount is the coolest and the card that is back-to-back with the bottom slot card is still getting really hot (and loud). But It's definitely an improvement over a normal quad layout.

    EK Custom Loop high temps

    Are you P-state overclocking? This can drastically reduce your idle temperatures. And Load temperatures will depend on your Vcore voltage and how aggressive or not your LLC is. Personally I recommend HWinfo64 to monitor your temperatures, RealBench for a whole system stress test, P95 blend for CPU only stress test, and Furmark for GPU only stress test.

    emptied and refilled custom loop and now have foam

    Did you clean it with detergent?

    custom loop question?

    This is known as a parallel loop configuration. The flow will be uneven across the gpu and cpu, but given the pump is powerful enough is not a problem.

    Going All Out (BTTW)

    RAM cooling is not getting you anything apart from looks, and honestly youll only see a couple of degrees improvement from the 360 mm radiator. The only thing thay would be "worth it" in my opinion is if you put your gpy under water.

    my cpu is overheating

    Turn the pump on?
  22. After travelling over a Threadripper 2990WX overclocked to 4 GHz and the VRM to keep that stable, the fluid temperature increases by 1 degrees on my system. So as usual, order is not important, even after passing over a tonne of heat generating components

    Parts on the way for loop, any advice?

    Multiple reservoirs have no functional purpose. 2 pumps in series can be helpful but is often not required for standard loops using good quality pumps. Only if you have a real stinker of a pump and/or an incredibly restrictive loop, is it worth even considering. (and if the pump is a stinker, instead of having 2 stinkers, better have 1 decent one). I personally wouldn't use soapy water to rinse new components, hot tap water followed by water is my go to for new components. Soap could do not so great things for O-rings (since they are usually a bit oily) and reserve it for deep maintenance only. Air is never good for any system, so the ideal scenario is to completely fill up the system and have absolutely no air. Keep topping off the liquid until there is literally no bubbles whatsoever. This also prevents coolant degradation in some cases.
  24. Macro photography anyone?

      it always bothered me with electronics macro-shots/b-rolls shows how the dust just settles in at all the random spots , never seen a clean picture of an unboxed product ever.

      Yes its so true. This shot was even after a quick wipe, but the lighting catches so many specks.

    Sides of bends bulging

    You're bending the tube slightly too cold and also too narrow around the bend region, you need to heat up a larger region (i.e. more side-to-side)
