FX 8320 CPU Fan is slow even at 100% setting; causing unreasonable temps.

[secondchancebreath]

My System:
AMD FX 8320 (Stock Cooler)
GIGABYTE GA-990FXA-UD3

The CPU is not overclocked, I have it set at failsafe defaults in BIOS, but when I tested it on Prime95 the core temperatures went up to 67C within 10 minutes, above the 62C recommended limit from AMD. The high temperatures I can only guess are due to the low CPU fan speed: when at 100%, it only turns at 3700rpm!

I went into bios and turned off auto fan control, enabling 100% cpu fan speed at all times, and it only turns at about 3700rpm. This can't be right, can it? I mean, the stock cooler should be sufficient for running at stock speed.

3700rpm is really fast lol. maybe try reapplying some artic silver 5 thermal paste and also cleaning your heatsink and cleaning all the dust inside your system around fans and whatnot


Edit* 3700 is crazy fast it should sound like a hurricane lol

Stock cooler should be fine at stock speeds but prime 95 is about as hard as you can push your components. That's a really nice MB and CPU, just buy a 212. The 212 is really inexpensive and that processor is begging to be overclocked anyway.

3700 is slow? It's not very loud at all, and I saw other people discussing their stock 8320 coolers and talking about 4500 or 5000 rpm. For example, this thread: http://www.tomshardware.com/answers/id-1825536/amd-8320-stock-fan-speeds-temperatures.html

Yes, I'm sure I could grab a 212, and maybe I will, but I'm surprised that it can't even cope at stock speeds! Surely that can't be normal?

What are your ambient temps and did you apply the thermal compound correctly?

 

[Rangan Das]

I have the FX 8320 and during summer, the temps went up to around 70 degrees C in AIDA64 stability test. The stock cooler would go to 6400RPM. Everything set to default in BIOS.

Fact: the stock cooler is crap.

I got a CM Hyper TX3. Temps max out to 55 degrees or so. RPM is about 2000.

Well to increase CPU fan speed, try out SpeedFan. You can change your fan speeds as well as monitor the temps. Download it, open it, and you will see some fan controls. Increase and decrease to your need. (Note, GPU fan to 100 might blow your ears out, but will not cause damage to your system)

Or buy a good aircooler, like Hyper 212, and do this as well.

Get the 212, with some MX4 thermal paste.

 

[ohyouknow]

You really shouldn't be running prime on your stock cooler. Prime 95 is not an everyday measure of what you'll be doing. Check your temperatures while gaming or applications.

 

[Dark Lord of Tech]

I agree ^

 

[paitjsu sadff]

temps recoarded while running prime 95 or any other stress test should not be even considered, check your temps while you play your favorites games for prolonged period of time, no applications will ever make the 8 core on that beast calculate to a 100% for a prolonged period of time...
