5820K too hot?

It should realistically drop to about 40 then about 2 seconds later back to 30. If it's taking a while that tells me either the cpu is dumping a lot of heat or the pump is not carrying the hot water away fast enough.

Especially if you just run the test for a few minutes. Sounds to me like the pump is not running correctly.

1.25v is fine. 1.35v-1.4v is about the limit you want to put on the chip for 24/7.

Do you have an air cooler anywhere to test?
 
I don't have any air coolers to hand to test.
I'm not sure how i would tell of this pump is doing its job properly
It says on corsair link that it's running at 2940

Hi guys

I have 2 apache fans running at 100% located at the top of the radiator, pushing air down through the radiator. The h100i sounds like its nice and quiet. I have the pump running at 100%.
idle temp around 33 degrees
full load temp 85-92
Click to expand...

just a quick question. so you've got 2 fans on the case that push air inside the
case. Which way are the h100i's fan's blowing?
 
Running test now using Real Bench 15 mins and HW monitor, core temp to monitor voltage and temps

7mins into test: 85 degrees on core temp
1.219v
 
So guess what guys, my fans were pulling out air from the inside of my case!
Hot air rising through radiator and being blown out the top of case!!
I turned the fans around so that they are blowing fresh air down into radiator into case.
Running test now.
Full load 3 mins into test: 63 degrees !
 
Ps... This was a custom pc from pc specialist that was bought for me. Everything else is well built and well cable managed except for fans being round the wrong way!
Can't knock a gift horse!
 
So the test was successful with temps around 73 degrees! A big difference to say the least. Some times you just cant trust "pre-built" systems
 
Glad that's sorted it.
Odd though unless you have a volcano inside your case. I've ran a h100i in my old pc with 2 aftermarket 980s in. And had it mounted as a top exhaust. Temps were hotter but still no where like yours. You could feel the hot air through the rad.

In the top they are recommended to be mounted as exhaust anyway. As it's hard to push hot air down.

I suspect by removing the rad etc maybe you have dislodged a stuck air bubble or something. Allowing the pump to function correctly. Unless the inside of your case is that hot.

Yeah I'm surprised that has made such a big difference. I'd have thought normally a top mounted RAD would be used as an exhaust as naturally hot air will want to go up, not down.

Other than the two fans on the RAD what other fans are there on the case? I'm thinking it's possible you had no other case fans, or other case fans that were all also trying to exhaust. In both situations the fans wouldn't be generating much airflow as they would have to overcome a fair bit of resistance to suck in air from all the openings on the case.

I was going to suggest your pump had died (mine did despite the UEFI saying it was still running at full RPM but if that were the case I doubt changing the orientation of fans would make any difference.
 
Seems like it dude
2x120 fans pushing fresh into radiator and into case
3x120 fans blowing fresh air in front of case.
1x140 fan blowing air out the back of case

The 2 fans on top of the radiator made all the difference
 
I suspect something else wasn't right and was fixed when the fans were reversed. Can the pipes kink? Or a trapped pipe.
The optimum should be the 2 rad fans blowing out, all the others pulling in.
Can you post a pic of your setup with the side off?

Does the GFX card vent heat out of the back of the case or is it spewing hot air inside? I just wonder if there's so much heat inside the case that blowing out through the rads is worse.
