[SOLVED] CPU not cooling down

[Harinder]

After I cleaned my radiator (GTX H110i) today, my CPU (5820k) idle temps would not drop below 82c. +90c when just browsing chrome. Normally it is around 65-75c when on chrome.

I tried replacing the thermal compound but that did not seem to help.

Removed OC to default. - no help

To clean my rad I used a vacuum with bristles. Pretty sure that would not effect cooling performance..

I used a microfiber cloth to wipe PCIe slots, not the motherboard itself.

One thing to note - when I feel the two pipes leading to the rad, one is cool, and the other is warm. So I think the rad is doing its job. 

I don't think there is a program eating performance because temps are still 80+ in the BIOS menu.

Is your pump working?

Yes. Corsair link says the pump is around 3000. (whatever that means).

When reapplying the thermal paste, did you clean off the previous? I know silly question but this could definitely affect it.

Holy shit 75C idle temps! something is definitely wrong there, especially on water cooling.

Literally an intel stock cooler should be able to get 45C or so idle temps (while on chrome) so either your pump is broken or your radiator fans are not workiing

haha yes. i used isopropyl alcohol and a paper towel.

If your fans and pump is working correctly, I assume something in tube is blocking water flow.

Make sure you have your cooler mounted properly. I have done that before!

I followed this guide.

60-70 idle temps seems to be normal.

No. They really aren't. Feel you pump, is it vibrating when running?

Are we talking farenheit or celcuis here?

Those temps are ridiculously high.  My 5930K is cooler while benchmarking at 4.5GHz than your 5820K is on idle, and I'm only running on air.

 

As for one pipe being cool and one hot, that's not normal.  Even with the CPU being hot, the temperature in the loop should be fairly constant given sufficient flow.  So you definitely have a flow problem.  The pump may be running at 3000RPM, but that doesn't mean it's actually moving much water around if one of the tubes is blocking it.

 He mentions 82c and 90c, so I assume the "c" stands for Celcius.

Both 65-70 and your current temps are way, WAY too high. Idle temps should be <30 when speedstepping properly works.

Mine are 23-25 atm, and that's on air (granted, not exactly a Haswell-E CPU, but it shouldn't matter much in idle).

 

You're either still improperly mounting it, something is wrong with teh CPU block or the motherboard is feeding it retard-level voltages.

Try putting back the stock fan, and look at temperatures then.

[pyrojoe34]

My OCed i7-6800k with an h110i GTX idles at 30-35C and maxes out at 60C.

 

First, check my sig for a fix related to Link.

 

If that doesn't work, remount the block. But you have to do it outside the case, the tubes are very stiff and you won't get a flush mount unless they're perfectly relaxed which you can't do if you try to mount it in the case (I had this issue and dropped by temps 20-30C by remounting it carefully in a relaxed position.) Mount it first, then install the radiator/mobo in the case.

 

Finally, are you sure you're using the correct standoffs? If you're trying to use the AMD ones you wont have a good contact.

oml im dumb. Ive been running at these temps for 6 months now... Ill try another remount as @pyrojoe34 recommend. if that doesn't help, I will contact Corsair, and hopefully get a replacement rad. Thanks for the help.

My cpu didnt come with a cooler. 

ill try to remount it and see if that'll fix it. if not then ill replace the rad. thanks for the help.

What method for thermal paste do you use?

[paddy-stone]

Are yo running an OC with no stepping, so it is overclocked all the time in other words? That's the only reason I can think of if you have all the hardware mounted correctly for these insane idle temps.

If you're OC'ing I would definitely reset CMOS and start again, enable stepping in the BIOS/UEFI for sure and then try to get your OC back to what it was. That way the CPU will lower the voltages etc when it doesn't need it.

Shouldn't matter really. Even if the OC was forced to remain at that frequency even when idle, it still doesn't explain why the CPU is idling at 75*C.

Yeah, I was just trying to even think of a reason and that's the only one I could think of that even came close.

Im pretty sure it was stepping, because at idle the clock speed dips down, but when I AIDA running, it goes up to 4gz.

Sorry, I meant what method you use to apply your thermal paste.

I suggest you do it like this:

1- Remove the desired cooler, CPU in your case, making sure to disconnect the fan, putting screws, if applicable, in a safe place such as a magnetic parts tray.  If you are using a air cooler set the cooler on a desk, with the TIM in the air... if you don't want to clean the desk. If you are using air then you might as well clean the whole thing while its out.

2- Clean off the old TIM off the CPU and heat-sink, using TIM remover and a tissue, making sure you have cleaned it all off. Don't be afraid if you have to do a second pass with the tissue and cleaner.

3- Wait a minute or two, for the cleaner to dry

4- Wipe over CPU and cooler with something non-abrasive ,your tee-shirt would be fine.

5- Make a line of thermal compound through the middle of the CPU parallel to the longest edge. You could do a pea or grain of rice but this gets good results. It dose not tend to matter what thermal paste you use. I have been using akasa and cooler-master for a few year and have never had any issues.

6- Spread the Thermal paste out, you want a thin coverage all over the CPU. This is to ensure that all of the CPU die is in contact with the cooler. If you don't spread it out well enough the the thermal paste will act as an insulator rather then a heat transfer method. If you are doing this to a laptop then it dose not matter if TIM goes on the green part of the CPU.

7- Place the cooler on the top and wait a minute, to let the air escape. Some people will move the cooler about but with this method it is not needed as you have sped the TIM out your self.

8- Tighten down the heat sink in a star pattern.

9- Make sure the cooler dose not move at all, need to be careful with this when using stock coolers.

10- Reconnect the fan.

This is how I do it. I have always had good results. Sorry if this seems really generic and if some of it does not apply. To save me typing it out again and again I store it in a .txt file and just copy it in.

hmm. So this is what it looked like when I reapplied the thermal paste the first time: http://imgur.com/gallery/KOxmf

(i put a bit too much) It seems like it made good contact, right?
