Too High Temperature?

stormforce · Jun 12, 2017

Hello, so few days ago everything was fine. So yesterday I cleaned my PC for dust. I vacuumed, I know I should have used something to blow dust out and not vacuum, but that's my bad. Today I noticed that my cpu fan is running a bit slow. I know that because it is a box fan and it is not as loud as before on full load. It just spins at the same speed. As I said I can hear it not speeding on higher load. I started up Battlefield 4 and it got to 100 °C.

Here are the pictures of the temperature:

I can't remember what temperature was before cleaning the computer, but the fan was running a lot louder. And now when I touch the place on the computer when the processor is located it is abnormal hot, at the point that I can't hold my hand for too long.

Do you have any idea why that is. I know its summer and everything but damn that's hot. I can't tell if it is a hardware or software problem.

You can see my computer specs in the pictures.

i would suggest to repaste the cpu cooler and in the same time check if you did not put out the fan blades from is base so cpu will get up and overheath if you have another fan around try it on the cpu cooler .

It could have been caused by static discharge. Using a vacuum on a computer isn't the best move. You always want to use a air duster (can of air). However, try resitting the CPU FAN in the header. Then start of Windows in safe mode. Does it give the same result?

So if your PC is running at that temp do not run it anymore you can cook a steak on that kind of temp. Also an issue maybe that your thermal paste is dry or cracked. if that stuff goes bad it can stop doing its job. Also check to make sure you have a good air flow through your case so any sort of wires or just random crap you want to make sure you have air flow like this https://www.google.com/search?q=computer+case+airflow&source=lnms&tbm=isch&sa=X&ved=0ahUKEwiG2NTr7rjUAhUFzGMKHSxzDyUQ_AUICygC&biw=1920&bih=974#imgrc=hP4tWBsKDy-8gM:

Are you able to manually adjust fan temperature curves? Either through utilities that came with the motherboard or a third party one? If you can adjust some fans but not others, it could suggest some localized damage on the board.

Sedivy :

Using the SpeedFan program I can only reduce the speed of my CPU fan. It is set to 100% so I can't get it to go faster. It looks like something is blocking it to go over 66000 rpm.

I should just replace the hole god damn cooler. Those default CPU Box Coolers are sooo bad.

stormforce :

If you do plan on switching out the cooler go liquid, you are running this thing pretty hot and liquid is good for that kind of stuff.

FuzzyPeaches :

Well it's not running always at that temperature. Currently it's around 65-68. It only get's that hot in games, like Battlefield 4. Maybe it is the paste but what is interesting that it wasn't that hot before I cleaned it. It is open on the side, but I only have 1 fan to get the hot air out.

Yeah I was thinking about liquid. It's not loud and it does the job of keeping the CPU cold. let's hope my PC doesn't melt before I buy new cooler.

Unfortunately I don't have another fan to replace, I'll check the blades, it may be that they got pulled out because of the vacuum.

Herc08 :

Maybe, I regret using the vacuum. I'll blow it with hair dryer next time. What do you mean reset the Fan in the header?

FuzzyPeaches · Jun 12, 2017

NO dont use a hair dryer use a can of compressed air. You can get thermal paste for like a buck at best buy. Take your cpu can off clean it with some rubbing alcohol and the CPU the portion that gets covered the paste. But about the size of a pea on the CPU and put the fan back on if its still running really hot then it could be you are running more then just the games you are playing.

Sedivy · Jun 12, 2017

Ok if your fan speed is 100% then you're ok with regards to fan function. I thought you said that your cpu fan was running a bit slow even though temps on the cpu were high. if the fan is going at full tilt and the temps are still high, and are higher than they were before you vacuumed, then likely during vacuuming you tilted the rig, or you nudged the cooler and now it's not sitting properly on the cpu anymore.

Basically unmount your cpu cooler, clean off the thermal paste carefully, reapply new one, and re-mount the cooler. Tighten the screws and then start it up and check the temps.

By the way, cpu fans generally are pwm 4 pin fans. What that means is they typically don't run at 100% all the time (unless there's something wrong with the cpu, like overheating), and they should go up and down with the temperature of the cpu. If this is not the way your cpu fan responds, there could be an issue with a setting on your motherboard (eg. you have it set to DC instead of PWM for that fan plug) or that you have a dc fan when you should have a pwm fan and so on. But I'm assuming this would have been issue before vacuuming so presumably this isn't what's happening in your case.

Sedivy · Jun 12, 2017

Oh, instructions wise on how to reapply thermal paste, you can find many youtube videos but I'd find one that shows it specifically for your cooler so you are sure what to do and there's less confusion.

stormforce · Jun 12, 2017

FuzzyPeaches :

I'll try and replace the paste tomorrow. And next time I'll check in the processes if something is using processor behind the game.

stormforce · Jun 12, 2017

Sedivy :

Thanks for reply. What I meant is that before the cleaning when I start a game I can hear the fan ramming up and the noise was huge but I got used to it. So now when I start a game that is stressful on the CPU the fan noise stays the same as on idle. I just know that that is not 100% of the speed, because I know the noise it makes on 100%. But in the program it says it is 100%.

Maybe you are right, maybe I knocked something with the vacuum. I'll try to unscrew it and replace the paste. Maybe its not touching the CPU.

Sedivy · Jun 12, 2017

Well...that's a different issue though. Normally if you knocked your cpu cooler around, your fan would still frantically try to cool the cpu but to no effect so you'd have high speed on fan, very noisy, but still high temps. I'd still re-mount the cooler as that's something that you can easily do yourself, but if fan is just not spinning now anymore, then that's a different issue.

It means that whatever temperature/RPM curve that fan is supposed to follow, it's not doing it anymore for whatever reason. It could be that some sort of setting got reset so it's just a matter or readjustment. Support for this would be the fact that using SpeedFan, you can ramp it up, it just won't do it on its own. So within SpeedFan, you can actually set a temp/RPM curve that suits you and keeps the cpu within a reasonable temperature range and avoid 100C meltdowns that way.

If SpeedFan can't actually adjust this fan's speed anymore, that's a different issue, and then something on the motherboard may have gotten damaged, and this cpu fan controller is not functioning anymore properly or just not responding to changes in temps. That would be the static charge damage.
