60C on idle?

[aka_jace]

I bought a built PC a few months ago, and was going to start overclocking it earlier this week, but when I starting looking at temps, the CPU is running pretty toasty. It's an i7-5820K. I'm stumped on how to get it to acceptable temperatures in order to even attempt an overclock. At stock speeds, it idles at 55C in the BIOS, and at 60C on the desktop. It gets over 80C while starting windows. And in a 5-minute stress test in Intel XTU, it hits thermal throttle at 103C within 45 seconds. I've replaced the thermal paste on the CPU, and made sure that the cooler is seated properly. I've checked that all the fans are running, and have tried Turbo and Full Speed options with no noticeable difference. I've been using XTU to monitor temps.

 

Case: Phanteks Enthoo Evolv

Cooler: Corsair H110i GT 280mm

 

The case has two intake fans on the front, and one exhaust fan at the top rear. The AiO is top-mounted with four 140mm fans in push-pull that exhausts out the top of the case.

 

Open to any suggestions.

I mean, either something is very broken, temps are reading wrong (unlikely) or your chip is toast.

 

I have seen people not plug their corsair AIO's into power so their pumps never actually turn on. I forget off hand, but does the H110i use SATA power? If so, is that plugged in? And then the fan plug (its really the pump plug) coming from the waterblock/pump plugged into your motherboards CPU fan header?

 

If yes to the cooler being plugged in correctly its likely the pump is bad. But, unfortunately, depending on how long it has been like that your CPU could be hurt now as well

Yes, SATA power, and it is plugged in. And the pump cable is plugged into the CPU FAN header. If the pump is bad, would the LED on the Corsair logo still light up?

did you remove the plastic? turn off the fans, and can you hear the pump?

It would still be receiving power but the pump itself may be non functional. 

Isolate it, unplug every fan and remove the gpu, unplug mechanical drives

then turn it on and listen for pump noise, if it's silent, its dead 

 

you can also do this by removing the cooler, using any separate psu to power it and jumping the psu on just so you can really get an ear on the pump

 

high temps like that wouldn't have damaged the processor, That's why they thermal throttle, it can handle a lot more than 103c

I unplugged all fans and the GPU. After powering it on, there is a VERY faint hum coming from what I assume is the pump. Not sure how much vibration/noise its supposed to make, but it is making more noise than when powered off. It's quieter than a spinning disc, and I can only hear it when I have my ear less than 3-4 inches from the pump.

So on the off chance the pump is alive, is it too tight? Aios have a thin contact surface and if the mounting is too tight it can cause it to make a concave shape which leaves poor contact in the center of the cpu IHS

I loosened the pump mount and tightened them to thumb-tight. It does seem to have made a slight difference in temperatures (not really at idle, which is still around 60C, but peaking around 92C on full load, instead of hitting thermal throttle in a 5 minute XTU stress test.) The ambient temperature of the room has probably also gone down 1-3C.

 

Couple of side notes:

iCUE shows ~2390RPM for the pump.

The radiator doesn't feel warm to the touch while running the stress test, and the exhaust air from the AiO doesn't feel warm either.

Attached video is right at system startup. I start OBS to record, then run a 2-minute stress test in XTU.

 

*EDIT*

After checking the coolant temp in iCUE and seeing it around 60-70C, I've decided you're probably right about the pump. Reached out to the guy I bought it from to see if he has a receipt so I can RMA. Thanks for your help.

UPDATE: The guy that I bought it from never got back to me, so I went ahead and just bought a new AiO from Best Buy. They had the 280mm H110i on sale for $90, which was a pretty good price anyways. 

 

After installing everything and booting up: 24C in the BIOS, and 28C on idle at the desktop.

After messing with overclocks for a bit, I got 4.3 GHz stable at 1.418v with peak temps in a 2-hour XTU test of 82C.

 

Thanks for the help, campy!
