Warp damage possibly causing overheating

theiDunnotouch · Aug 17, 2017

So I've just splurged a bunch of money on an NH-D15 but while waiting for the cooler I decided to install the stock cooler to get some work done.

Needless to say the PC started overheating under stress.

55 degrees idle
100 degrees load.

The PC shuts down after extended loads, it immediately shuts down when temperature spikes happen.

I know this is a stock cooler but it's just not normal. I uninstalled the stock cooler thinking that it might not have seated properly, when disassembling though I found that the CPU socket area is warped
Could the warping have caused a concavation of the mounting points thus causing an improper seal between the cooler and the cpu?

Mobo is a Maximus VII HERO
Cpu is an i7 4790k

did you put any thermal paste between stock cooler and cpu .

theiDunnotouch · Aug 17, 2017

Of course! NT-H1 thermal paste, small dot in the middle, double checked and triple checked the stock cooler pins that go through the motherboard

the cooler was well seated did you check if it run loose when fan spin up and also check if an do is job under load use hwinfo to see it also could you poat a bigger picture of the first on with cpu base on the board .

So I installed an NH-D15.
Prime95 small fft reaches 75 degrees tops, sits at about 70 degrees. 65 degrees while playing Witcher 3.
The problem though is that the heatsink is cool to the touch, only gets slightly warm. I've tried reseating countless times... Maybe time to delid and lap the IHS?

dont forget to check if the cpu fan cooler speed up as temp raise .

theiDunnotouch · Aug 19, 2017

CPU fan speed is in check and functioning properly.... Still, these temps are too high for such a cooler at stock clocks

scout_03 · Aug 19, 2017

100 on load if it is celcius that is to high would recheck paste on cooler and see if it is not moving from cpu when fan speed up .

That was with the stock cooler. I slapped on an nh-d15 and topping 70 degrees with prime95 small fft and idling at 40 degrees. Ambient is 30 degrees. Tried reseating numerous times

then with nh-15 you stay at max 70 c on prime you should be good what is the air flow in this case .

Corsair Obsidian 750D.
Two intakes, rear exhaust, blocked top portion.

scout_03 · Aug 19, 2017

what is blocking the top since it could handle 2 x 140 mm or 3 x120 mm fans .

scout_03 :

I just put the dust filter it comes with, used to have a radiator up top.
The things is, that even with water cooling I'd still have these temps, I think something isn't right with the IHS...

scout_03 · Aug 19, 2017

the water cooler fans where set to push hot air out to the fin on top . also cpu warped could be due to overheath since lack of cooling paste between cpu and cooler every time you remove cooler you need to repaste .

theiDunnotouch · Aug 19, 2017

scout_03 :

I don't have the water cooler anymore, now it's just the nh-d15 with the mentioned temps

scout_03 · Aug 20, 2017

with previous temp on prime under load you could go with it but i would shurely increase air flow in the case to lower it even a few celcius down .

I've been doing some thorough testing the last few days and still have the same problem: tried with an nh-d15, cryorig r1 ultimate, intel stock cooler.
The stock cooler just ramps up to 100 degrees in any stress test and the CPU starts throttling
The Cryo and the Noctua keep it under control at about 75 degrees max on stock clocks, the problem is that the actual heatsinks don't heat up which means there isn't a proper heat transfer going on.
Tried XSPC thermal paste, NT-H1, Cryopaste CP9 and Arctic MX-4, tried reseating countless times and still the same problem.
Used CPU-Z, Real temp, Core temp, HWmonitor to check temperatures, all report the same temps....

then it could be with the wrap that hte cpu and sensor got it you might gone need a new cpu .
