CPU Overheating Randomly

[PL4Y3R_0N3]

I’ve been scrapping together older parts to try to build a decent system on the cheap. I got it together and in working order, and everything seems fine, until one day while I’m playing Siege the fans ramp up to max for seemingly no reason. I pull up Open Hardware Monitor and behold, the CPU is at 90°C out of nowhere. Now, it’s only been a few days since I got it together, but earlier in the day I ran a 30 minute test on Cinebench R23 and the temps never got over 70°C, everything seemed fine. I figured it was just the radiator didn’t have enough cool air passing through since the GPU was hot too, so I went into BIOS and threw the front case fans to max and left them there. But now, any time I boot up the CPU gets blazing hot for no reason. And I don’t think it’s bad contact because in iCue the water temps are launching to over 45°C now. I thought maybe the Pump was bad on the old H100i I had but I tried another H100i and the temps are even worse. Now I can’t even boot the system without it launching to 90° right off the bat. I haven’t changed anything, what the hell is going on?

 

Current Build

i7 6700k

corsair H100i

GTX 1070ti

Asus H110m-c

EVGA 600w power supply

 

I have one more thing I can try and that’s replacing the H100i with a cooler master hyper 212 evo that I have, but I genuinely don’t think that’s the issue as it was working just fine before.

Update:

so I saw a Reddit post about the h100i having issues with blockages and the quick fix they suggested was to smack around the tubes a bit to get rid of the blockage. That’s not a long term solution, but it worked for the moment. Is there a way to clean this thing out? The pump sounds gritty, but I don’t want to buy another cooler when this one can work really well when it’s not blocked up.

no, its usually never worth going through the hassle of opening up a sealed aio.

 

Also it cant work really well remember? Its got a blockage.

You haven’t answered my question and you also provided no useful information, but thank you.

I recognize it’s probably “not worth the hassle” but this isn’t about hassle it’s about not throwing out an AIO I could fix myself. 
Also my guess is that it has a blockage, I’m not entirely sure that’s the case. It happened on both h100i’s that I have, so either they both have a blockage or something else is at fault. I know the CPU fan header works because it worked on the CoolerMaster, and I’m pretty sure the USB port I have it hooked into works as well because iCue can measure the coolant temps. The pump seems to be working as far as I can tell, the radiator gets warm when it’s running under load. Right now I’m sitting at 22°C idle, but 10 minutes ago I hit 100°C playing siege, and this happened before I could even complete a TH. Swapping back to the first H100i now since it didn’t seem to have nearly as many problems as this one does.

No, if its faulty you cant fix it yourself.

Can you feel the radiator getting warm when the temps are extremely high? Does it seem the right ratio of warm to temps high if u know what i mean.

 

Like if cpu is 100 degrees, does the radiator feel like its dissipating all that heat? And whats water temps like when ur cpu was 100c.

 

Considering wacking the radiator made it start working, i feel like that says enough about if its a blockage or not. 

 

Actually how is the radiator fitted? Can you send a photo?

The radiator gets warm when the temps spike, and the coolant will get up to 45-48° when the CPU is at 100 for a few seconds. It doesn’t feel like it’s actually dissipating much heat though because the coolant temps remain very high even after you take the load off the CPU, and the air passing through doesn’t seem that hot. I know on the h60 that I was using on my main rig the air passing through would be toasty, the temp doesn’t seem to change all that much for this one. 

When I have no load on the CPU it will idle at ~26. Now when I whack the hoses nothing seems to happen. This applies to both coolers, although the fist one (which I have on the system now) is working a little better than the other. 

This is the only orientation for the cooler that will fit in my case. I have the radiator the right way (thanks Steve).

Orientation seems fine, if u mount it on the other side sometimes aio motor doesn't get enough water because they are not fully filled.

 

From all I can tell then, there must be a blockage which won't be possible to fix yourself unfortunately.
