Troubles with CPU Fan Speed

by ekdy / March 26, 2015 6:59 PM PDT

I'm pretty clueless regarding the advanced stuff about the computer so I thought I'd see if this forum could help me out. My CPU temperature get pretty high (77~85 degrees Celsius) and I thought I'd try and get my CPU Fan to run faster to cool down the CPU so I tried using SpeedFan. I monitored the temperature, CPU Fan speed and CPU usage and it seemed like my fan ran faster as my CPU usage increased instead of the temperature so I tried to fix that by following some instructions on the internet to make it so that CPU fan speed increases as the temperature increases. However that didn't really seem to work.

Can you guys give me some step by step instructions on how to use SpeedFan or another program to increase my CPU fan speed?

Heating issue
by pgc3 / March 27, 2015 12:22 AM PDT

More information on your hardware might help...L/T Desktop? Hardware parameters, CPU,PSU,GPU, Is the unit being overclocked? Again, more info could help.

desktop, cpu - nuvoton nct6776f, gpu - ati video card, psu 450W (?), no overlocking. computer is about 4 years old or so. that's about all I know. if you require anymore information i'll try my best to find it out.

Clean PC
by Willy / March 27, 2015 12:58 AM PDT

Since, you stated its 4yrs. old, have you ever really opened it up and truly cleaned it? Not only that at 4yrs. the thermal cpu paste should be refreshed(clean and re-apply) for best results. Clean the overall PC 1st, then check results. Yeah, details matter, use PCWizard 201? pgm. to check your system stats.

Tried that

In reply to: Clean PC

Cleaned my pc out roughly a week ago after my computer kept overheating. I also noticed that the thermal paste was dried up so I cleaned it and reapplied a few days ago. It's gotten a little better but when my computer is idle it gets up to 77 ~ 85 but when I'm playing video games that increase my CPU usage quite a bit the temperature goes down to about 50 ~ 60

That's bad news.

Did you try it with the cover off and are the fans spinning normally? At 4 years they may need replacing as these do fail over the years.

I have the cover off at the moment and the fans are running fine. It just doesn't run that fast according to SpeedFan. It's running at 1380 ~ 1500 ish with the temperature jumping from 60ish but mainly staying in the 80s

I'd try the cheapest thing possible.

Replace the fan on the CPU/GPU that is getting hot.

How much would a decent fan cost? Perhaps give me some recommendations as I don't know anything about computer parts

From a dollar to maybe 100.

In reply to: Price

I've seen fan costs all over the map. It may be cheap in say San Francisco to exorbitant in the Antarctic. I can't guess the costs but given the story it's sounding grim unless the heatsink work was not done well. That is I've seen such and the heatsink wasn't in full contact causing a lot of pain for the owner.

Parts can fail like this and the cost at the shop counter may be greater than a replacement.

I'll look around

I'll try and search for a good replacement for my fan and perhaps I will reapply the thermal paste in case that was the problem. Cheers

I find that many get the paste on right.

Scanned already
by ekdy / March 27, 2015 2:17 AM PDT

My friend told me about how it could be bitcoin miners that are running when my computer is idle and told me to download MalwareBytes to scan my computer. I installed it recently and scanned my computer and there were a handful of files that got removed but the situation didn't improve. I believe it could be just that the heatsink does not have firm contact with the cpu and so its not cooling down that much. I'll try and push the heatsink more in and see if it will help out.

I use compressed air
by Willy / March 28, 2015 2:16 AM PDT
In reply to: Tried that

I realize not everyone has that and generally most other cleaning does the job. i do find though, when i do take "my time" to clean, the results can be very different. I have blown out PSUs and these still reeked of dirt and that more powerful compressed air, gets dirt coatings off as well. If the problem remains after all that, then either a fan just isn't cutting it or bad then I'm able to locate the possible cause. i found the PSU fan itself bad. it just was stuck or failed and that is usually 1/2 of basic cooling for most PCs. The other being the cpu and gpu fans or heatsink combo. let's not forget any possible vent clogs at frt. behind the frt. panel/cover. Worse, if filtered or possible dirt clogs again. Within reason, leaving nothing to chance and blow out all areas and touching all cooling methods, etc.. good luck

At that age it's time to
by R. Proffitt Forum moderator / March 27, 2015 1:00 AM PDT

At 4 years it's time to get in there with the canned air and get it clean. It's also time to replace the old heatsink compound.

BUT some machines never did the fan speed according to temperature trick. That's something new for some gear however 77 to 85 C is pretty high. Too high IMO and a sign it's time to do the cleaning and heatsink work.

Yes, a lot of folk will just buy a new PC.

connect the CPU fan
by James Denison / March 31, 2015 4:56 AM PDT

direct to a Molex power output from the PSU. That's as fast as the fan will ever run. You might need an adapter for it, or take a fitting off an old fan and splice it onto the wires from the CPU fan. Expect more noise from it.
