Tweaking Fan Speed

Gigazombie Cybermage

So, I decided to use gpu-z to see exactly how hot my Radeon 6770 HD runs while I game. Normally, when I check it after playing something it registers mid 80c. However, when I was looking at the log file and it got almost to 100c during play! (Basically, 97, 96, 98, 94, etc.) Way, way too hot. Now, normally I would consider getting another fan, but there is no room whatsoever for it in the case. I have no clue how to tweak my fan though, never done it before, and I want to do it correctly and safely. I'd appreciate any help.

Well if you have your case fans plugged into moles connectors they will run at 100% all the time. How many case fans do you have currently?

Another thing you can try is taking the plates/covers off the other pic brackets on your case. This can help the graphics card get more air.

you can make the card fan spin higher than the automatic speed. Catalyst control center, overdrive page.

In most cases you will want those slots covered to ensure proper airflow over the electronics. If your case does not have intake and exhaust fans then you can try it. But if your case has intake and exhaust fans, leave them on.

I appreciate the help guys!

for the case fans, I'd also look in your BIOS. Usually there's fan settings in there, sometimes what amounts to a calibration program where it can check the max possible speeds and then adjust accordingly.

Maybe it's only running your fans at like half cause it doesn't know any better.

Speedfan may be your friend. Here's a how-to that worked for me setting it up.

First thing I'd do is check for dust buildup on the card. At stock speeds, video cards rarely push 90c. Get some compressed air in that mother.

Yeah, I've cleaned it. No dust. Maybe it just runs hot? I haven't overclocked it or anything. I will say though my room is horrible for holding heat in. Really stuffy in here. I have to leave the door open and have a fan going most of the time during the summer.

Maybe try the box-fan method? Just pry off the case side and run a full-size fan into the internals; see how the heat changes. If it drops, adding some case ventilation might help.

Some quick google-fu shows that your card is notoriously hot, though. 90c is more or less standard, so your temps aren't too far out of line. Worst case scenario, buy an aftermarket cooler for the card and use that.

Yeah, I'll keep an eye on it. It hasn't ever passed 100c yet, so I should be okay.
