hi
I have a fx 4170 amd cpu
Today I opened the case and saw a lot of dust at cpu fan,i detached heatsink and cleaned it with a little wet cloth.and also detached fan from sink and cleaned it too.a small slice is in the sink that i don't know hom to attach it again.
Now When i use normal works no problem there is,but when i start a run the speed of fan goes higher and higher constantly and pc turns off itself.
I didn't change fan cables.
Maybe its related to that slice?
Or the silicon material layer between cpu and sink?should i replace it?

I am not sure what the "slice" is that you are referring to, but it certainly sounds like you are not getting adequate cooling. Did you re-install the fan the right way around? Definitely clean off the old grey heat sink compound and put on some new stuff. You can buy thermal grease or something similar from computer shops.

Probably not. Read this: http://en.wikipedia.org/wiki/Thermal_grease

Hi
I installed the fan like it was before.and used some RTV I had in home as thermal grease but the temperature is high.I have set it to 60 in Bios.i was set it 55 before.then it must be due to thermal grease? the old grease was dry and like powder but was working good.

I used RTV as I told in another thread but seems haven't had much effect.
when I'm in Bios temperature goes high constantly.but in Ubuntu only rises when I run a CFD case.is this manner natural in Bios environment?

now I removed old grease and used some RTV Silicone and also have increased threshould to 60 in BIOS, now it doesn't rise the speed of fan during run at all!
the heat sink pipes are somewhat cold when idle but get warm when I set a run.
and I noticed that graphic card has turned very hot that can't stay to touch it and also the motherboard and NP are so hot(both when idle).
maybe heat is transferring through the motherboard instead of heat sink?

I don't know how to install cpu fan correctly(I think it maybe not installed properly)
a rectangular slice(with two small rectangular empty portion) is between fan and heat sink that I'm not certain should be put where on sink.
please guide me if you have Fx series(I have Fx-4170)
or is there a link about installing cpu fan and heat sink with pictures from inside of fan and sink when sparated?

Greetings to all!

@Ehsan: I've merged another thread that was related to this one. Answering some of the questions:

This has been answered in the past: http://superuser.com/a/102154
In summary: do not use toothpaste, unless you want to risk loosing the CPU and the motherboard.
Although, if you're feeling experimental, then you need to first scientifically analyse how your toothpaste behaves when exposed to heat and so on.

This is so ironic . You should not have removed the heat-sink without asking first! And you should have not removed the original paste, even if it was already a bit bad. It would be better than nothing and you could have asked how to keep it at low speeds of 1.5GHz at all times, so that it wouldn't overheat!
In addition, it's usually possible to clean the heat-sink and fan with the help of a vacuum cleaner and a small brush... (edit) without needing to remove from the motherboard.


If this is the stock AMD CPU cooler... on Youtube there might be some videos on how to assemble it... although I haven't found any


My advice right now is to not use the computer until you get proper thermal grease, designed for CPUs.

As for the graphics card, it usually does run hot, ~30-40ºC in idle. But there is a possibility that in all of the confusion of opening and changing the heat-sink of the CPU, you might have displaced something in the graphics card. Did you remove the graphics card, while you were doing maintenance to the PCU's heat-sink?
And were you careful with avoiding static discharges?
Far likes this.
