Loud 1090T fan, new to cooling, would appreciate tips

post #1 of 2
Thread Starter 
I just installed my new Phenom II X6 1090T, and the fan is driving me nuts. My previous CPU in the same PC, a Phenom II X3 710, was also using stock cooling and was always quiet, even at full load. This one is loud even when the system is not using much CPU power.

It's the first CPU I installed in a while, so it's possible I did it imperfectly. Yesterday the ambient temperature was 32C, and Fan Control in AMD OverDrive showed 51C and 5400rpm for FAN0. Today it shows 10C and no fan speed and no FAN1, which is showed yesterday, so I have no idea what's up with that.

Still, 5400rpm sounds true considering the loud noise. Can't tell about the temperature. Core temps are currently 45C (ambient 30C). All cores are at or over 3.2GHz, even though CPU usage is around 25% according to the task manager. Turning off GPU folding reduces CPU usage to about 13% and temperatures to 35C, and fan noise is a more tolerable but still loud.

That's on Vista Ultimate 64 bit. Motherboard is Gigabyte MA790X-UD4 with latest beta BIOS. Cool & Quiet is on. When I took the PC out of sleep today it was decently quiet, but after a reboot is was again noisy. By the way I also tried underclocking and undervolting in OverDrive but it didn't really help.

I also checked just now using SpeedFan now. There are a few fan results, two returned by "SB 7xx/8xx PM2" and two by "IT8720F". The first of IT8720F is the one that's over 5000rpm. Can anyone explain about this.

So first of all, any idea if it's working okay? I find it strange that using 25% CPU all cores would be at max normal speed or more. Do the temperatures I mentioned look normal? Is it possible to tweak things to make the CPU work less when it's only partially used?


Anyway I decided that I'll buy a low end cooler to replace the stock one (unless a magic tip here makes my problems go away). That would likely be the Scythe Katana 3, which is cheap (half price of the CoolerMaster Hyper 212 Plus at a local store, according to its website), looks reasonable and should be available locally. (I'll call and ask if it's available and if there's a reason for the low price; it doesn't say "retail" on the site unlike the other coolers.)

I've never used 3rd party coolers before, nor installed any coolers at all for that matter before this 1090T stock cooler. Last CPU I installed on my own was probably the Celeron 300A, and that came on a card. I certainly have never removed a cooler from a CPU and installed another one.

So I'd appreciate some tips about this. I assume I need to remove the cooler, clean the CPU, apply thermal paste and then put the new cooler. Any tips about cleaning and the entire process? Also, I have the Phenom II X3 and its cooler. If I want to reuse them in another PC I assume I have to clean them both, right?


Any thoughts would be appreciated. Thanks.

Yeah, it's pretty noisy.

The H50/60/70/80 are an easy bet if you want more silent, liquid based cooling.
