Re: CPU Overheating - Liquid Cooling

Is the CPU temp reaching 100 C or the GPU?
If it's the CPU temp. stop using the PC until you resolve the issue!
A likely suspect is the liquid cooling. Insure the pump is running and the liquid is circulating.
My best suggestion is to get rid of the liquid and use the OEM heatsink if you have it.
Liquid offers no advantage over air for normal use.
Is this perhaps an online built PC?

 

Re: CPU Overheating - Liquid Cooling

Thanks for the reply Tyree.

It's the CPU. The GPU never gets above about 33c.

I did test the hoses for the cooling and it does appear to be working..as the hoses are opaque and therefore I can't see the liquid is there any other way to test?

 

Re: CPU Overheating - Liquid Cooling

Sorry I forgot to answer your other question.
I ordered it built from a store that do custom builds.
It came with the liquid cooling so I don't have a standard heatsink to test.

 

Re: CPU Overheating - Liquid Cooling

You have to insure the cooling system is working. Feel the lines going to and from the CPU heatsink and see if they are both about the same temp.
My best suggestion would be to replace the liquid cooling with wither an OEM or aftermarket air unit.
Liquid cooling is about as useful as 16GB of RAM.

 

Re: CPU Overheating - Liquid Cooling

With all due respect, mentioning the fact I have only 16GB of RAM is about as useful as repeatedly missing or ignoring the fact that I've already checked the cooling system and it seems to be working fine.

I've had this system for over a year and this is the first time I've had any issues with it. I'm not suddenly doing anything with it that I haven't done in the past.

If the cooling system wasn't suitable for this build in the first place I assume I would've been having problems way before now.

I hate sounding like I'm complaining about free advice, but before posting here I took the time to search the forums and it seems that 'get rid of the liquid and use the OEM heatsink if you have it. Liquid offers no advantage over air for normal use.' is pretty much a go-to response in similar cases.

What I'm trying to do at this stage is rule out everything else but the cooling system, because, given that this is the first time I've had trouble with this computer, I don't want to replace it if I don't have to, and certainly not if it isn't actually what's causing the problem.

The main cause of CPU overheating is the CPU cooling apparatus not working properly and/or the thermal paste is dried. Insufficient power can cause an issue but your PSU is "decent" quality so it "should" be OK. The only test for a PSU is substitution.

It's highly doubtful the thermal pad has dried in one year making the cooling system the primary suspect.
Once again, you have to insure the cooling apparatus is working properly. You say you've checked the cooling and it seems to be OK yet you don't say how you have checked to insure the coolant is actually being circulated.

 

Re: CPU Overheating - Liquid Cooling

if your cooling system is working properly then your cpu would not overheat unless it isn't fitted to the cpu properly.

A cpu getting hot would not affect the graphics card but the cpu would throttle and slow things down.

If you have moved the cooler you will have to reapply new thermal paste after cleaning off the old paste.

I would suggest you try and remove the main cooling part of the cpu andyway, clean off the old thermal paste from the cpu and cooler and re-apply new thermal paste to the cpu.

Its not that we say liquid cooling offers no better cooling than air for no reason because in reality it doesn't. My air cooler is much better than some of the liquid coolers out there like the corsair 100 malthough its not better than the 100i but were only talking 2 degrees c.

EDIT also a dodgy psu can cause overheating, check the voltages and temps in the BIOS.

 

Re: CPU Overheating - Liquid Cooling

Hi and thanks again.

I've checked the heat differential between the hoses attached to the cooler...one's warm one's cold. Might do a bit more poking around and double check that everything's seated properly.

Re checking the voltages and temps in the BIOS, I'm not sure what I'd be checking? Do you mean the BIOS will state what the voltages and temps should be and I can check that against the figures I'm getting from CPUID HW Monitor?

On that note, here's a screenshot of CPUID after I've been running for a while. I've been avoiding intense processing but cranked it up a bit for testing purposes earlier which you can see in the Max temperatures column.

 

Re: CPU Overheating - Liquid Cooling

The CPU temps are obviously too high. You can try reapplying a fresh application of thermal paste.

 

Re: CPU Overheating - Liquid Cooling

the bios is most accurate, check for the 3.3v, 12v and 5v and the temps also.

If the temps in hardware monitor match the BIOS then your cpu is definetly overheating and could be getting damaged.

 

Re: CPU Overheating - Liquid Cooling

Installed new ThermalTake NiC F4 cooler.

It's topping out at 43c during the tasks that used to kill it. Idling at between 24 and 36.

The liquid cooler is still under warranty so I'm going to send it back and tell them what I think of it.

Thanks for the advice everyone.

PS: this cooler also seems to be very quiet by the way.

 

Re: CPU Overheating - Liquid Cooling

Glad you got it resolved and thanks for posting back. Now you have no concerns with heat or leakage. :smile:
