CPU cooler problem

[djcristy]

Guys I have a bit of a problem with my cpu cooler. 

First of all im using an MSI 970A-G43 with an AMD FX4300 cpu

The problem I have is with the cpu cooler. I use an aftermarket cheap ass cooler because the stock one was too lowd. The cooler I have now uses a 3 pin conector.

I red 10000 forums and almost everywhere i saw ppl saying that even a 3 pic cpu cooler can be controlled my the motherboard. I tried tweaking in bios and all kinds of software i can't make my stop spinning at full 2000 rpm

After 3 months of use the cooler started making some horrible noise when i start the cpu and i can only make it stop by smaking my case pretty hard because its making me crazy.

Please help: can a 3 pin cpu cooler be controlled so that it doesnt spin full speed even when the pc is idle ? is this the fault of the cooler or my motherboard is having some problems with the bios ?

PS: sry for my english im from Romania (eastern europe)

PS2: my cpu temperature in bios when i start my pc goes from 45deg C to sometimes 50-60 deg. C, but all i do is look at the bios. With software like cpu temp i checked the temperature and its something like 30 deg at idle and goes to 55-60 at full throtle. Is my motherboard reading the temperatures wrong and thats why my cooler is always at full speed ?

The bios can only control your fan if the fan supports PWM

 

Most likely, due to the cheap cost of your fan, it is voltage controlled.

 

You'll need to replace the fan with a PWM version, or get a fan controller.

ok 1'st problem solved and i was kinda thinking at that. but that temperature spikes in bios gives me some trouble too, when i think that the cpu cooler is already at full speed and it doesnt do anything ...... btw my cpu OC'ed at 4.1 Mhz using OC genie auto functions so i havent tweaked it manually in any way

I'm pretty sure it should be controlled if its in the CPU fan slot. The computer controls that slot I think.

You have to switch the settings in the bios from PWM to Voltage and that should control the speed if it's not a PWM fan. You also have to make sure it is plug in correctly to the header.

 

Try using the bios to OC instead of the OC genie. Also set your ram speed, timings, and voltage to what is listed on the ram.

i really dont know what to do. i will buy a better cooler because this one i dont think it will last 3-4 months more since the fan spins at 2000 rpm 7-8 hours a day .... but if the new cooler doesnt get controlled either im thinking of sending my mobo to waranty ...

i really have no idea how to change the settings from PWM to voltage in the bios, i looked but i didnt find anything like that in the bios. and about the OC i dont even need, but since the oc genie did that for me with just 1 click, and the system is stable, i left like that.

my ram is at 1432 from 1333mhz stock and doesnt go higher, i tried and i had to reset the bios cuz the pc wouldn't boot anymore. and for the cpu i dont trust this cpu cooler so im not going higher then 4ghz.

If the stock ram is 1333 at 1.5 volt then you may be able to push it higher but you will usually need a raise in Voltage and loosen the timings. That often negates the ram speed increase. Once you get the new CPU cooler on. Try to OC in the bios and set FSB to 200 and only use the multiplier until you get more familiar with overclocking.

 

 

Unfortunately, some of the MSI boards dont have LLC, so OCing is going to be a pain.

isnt pwn 4pin?

well those are some cool tips about OC'ing. thank you. i will definetly try that after a get a new cooler. just for fun. because all i do at my pc is to watch linus videos and streams and play League of legends. and i would love that my pc wouldnt sound like a jet plane when i watch a youtube video. you are probably right about the fan being voltage controlled because when i set the cpu_fan profile in control center it shows the fan slowing down acording to temperature but the speed readout is still 2130 rpms, so probably the cpu_fan controlls only PWM fans

PWM: 4-pins, controlled by PWM (duh), 4th pin provides PWM control

Regular: 3-pins, controlled by voltage (requires compatible board or a fan controller), otherwise at full speed, 3rd pin provides RPM readings

2-pin: you can't do anything.
