CPU over heating

MaddLu · Jun 22, 2016

My cpu is over heating only when I play videogames. It's like in the high 70s in c. My uncle who works with computers says the best thing to do is get case fans. (I dont have any only my cpu fan if your wondering.) So Im wondering is what fans should I get for my situation; where to place them. Heres the spots available:
top: 120 mm x2
Front: Blue Led 120mm or 140 mm fan
Rear: 80/90/120 mm fan
Bottom: 80/90/120 mm fan
Side 120 mm
As well as should they all be blowing in cool air or sucking out hot air. The pins available are 3pin pwr fan; 4pin and a 3 pin for sys fans.
Thanks

For starters lets get your system specs first.

1.What type of computer do you have retail or custom built ?

2.How long have you own the machine, what OS do you by chance ?

3.Which Motherboard do you have, also which type of cpu does your system have ?

Also you should comment if you live in a dusty area, I do, so I know how bad it can be for PCs and even more when you have several case fans.

Most likely you could also need an aftermarket cooler, but first answer maikutech's questions, the more detail the better.

maikutech :

1.Its Custom
2. The machine is about 3-4 years old; the OS is windows 10
3. The mother board is "The Ultra Durable Motherboard Ga-990FXA-UD3. For the CPU I could only find "AMD FX-6300 Vishera 32nm Technology" Hopefully that helps
Also I dont think its dusty. There is no dust on my computer and I havent dusted the out side for a while.

Ok then when was the last time the computer grease or thermal paste changed ?
Depending on the after market cooler and the paste, most will hold out for a year others 6 months at a time.

maikutech :

Its a cpu fan not a liquid cooler. But if you still talking about a cpu fan then probably never.

Krnt · Jun 22, 2016

I would recommend you to change the cooler if its stock, the stock for those FX CPUs are pretty bad, but a Cooler Master 212 evo should suffice, there are other options out there but for the price and for experience that is the one I'm sure works.

Aside from that I think you have mentioned the spots for CPU fans, but have not mentioned if any fans are present, a 120mm intake fan at the front and another one in the back should be enough, also you have not mentioned either if you have a video card present, depending on the video card your temperatures could rise enough to affect the CPU cooling performance.

Four years without any grease I can see why its over heating, anything past 69 degrees and your asking for problems as the cpu will die out over time.

You'll like these 2 items combined, I have a zalman on my computer, the installation is pretty easy.

Watch this so you will know to clean off the old paste, also when its off wipe it with green alchol on a little paper towel.
wipe it off and let it dry out for 10 minutes, take thermal paste and put 4 peas size on each corner of the cpu and one in the middle.
Take your right hand first hold the heat sink, slip the right side of the heatsink on, screw down the screw driver so its secure.
Take the other tab of the heatsink and put it on the cpu, make sure it touches the cpu socket latch.
Quickly have your uncle or yourself screw on the other latch.
Tap the heatsink some to make sure its not moving, if its secure and not bobbing turn on the computer.

MaddLu :

You should follow your uncle's advice; thermal paste doesn't go bad unless the cooler is dislodged. Even the best air cooler will have a hard time in a case that keeps hot air in.

maikutech · Jun 22, 2016

I don't think thats a smart choice, let the op decide what is best for him at the moment.
Sure he could go ahead and change the case fans, lets say its in hour later.
The tempature is still high and climbing what are you going to do then ?
His fx6300 runs hot, just like my fx6100 is the same, changing it every year is the best way.

If his uncle may play a game on it often, watch movies, home/office productivity and whatever else.
Grease will dissipate over time, not stay as it is since putting in upon installation.

MaddLu · Jun 22, 2016

I dont have any case fans in the first place. So Im not changing anything Im just adding fans to get it cooler. Well that's what I want to do

GhislainG · Jun 22, 2016

You selected a solution that only contains questions.

GhislainG · Jun 22, 2016

maikutech :

How many years of experience do you have? We never change the thermal paste even on systems that are 10 years old; fans are required to exhaust hot air from the case and that should be the first step. If that isn't enough, then a better CPU cooler is the next step. A rear 120mm exhaust fan should be added and ideally a front 120mm intake fan should also be added. His uncle seems to be a lot smarter than you seem to believe.

maikutech · Jun 22, 2016

Ghis I'm not here to debate with you or talk about or compare experiences.

MaddLu if thats what you want to do, go ahead and do so, however if the tempature does not drop below 60 degrees on full load or idling.
Take my advice that I mentioned earlier and get the heatsink/fan and thermal paste.
It'll do both of you a favor and it'll hold out for a year, its best to change the paste every 6 months to a year to keep it running perfectly.

Good luck.

Krnt · Jun 22, 2016

The thermal paste shouldn't be changed that often, but if you have the need to take off the heatsink from the cpu I would recommend applying new paste, its function is to fill the gaps between the CPU and the HS and they work better once they settle or dry out (depends on the material), but after that if you disrupt it, it is most likely to loose its effect, rising the temperatures considerably.

I normally change it once a year when I do a full cleaning of my heatsink.

Krnt :

Well thats how I change my grease, if you oc pass the original default clock speed.
Yes it will go out faster, my fx6100 by default is 3.3ghz, my max speed is 4.0ghz at full load.
I would say by late november or early december it will be time for another grease change.
Now if I didn't overclock, yes you are correct changing the grease 1 time per year is needed.
So it varies from time to time, but changing the grease is simple and keeps the chip for burning out.

If his tempature is high and he cannot stay on it for long, to verify his tempature this tool will do along with checking the bios.

GhislainG · Jun 23, 2016

maikutech :

It's an FX CPU; therefore we should refer to thermal margins that should ideally be 10 degrees Celsius or more at full load.

Im new to this website. Didn't know what to click. Was accident.

I think I may have contributed to that mistake, sorry.
