CPU overheating out of nowhere - Page 2

post #11 of 24
Thread Starter 
Not sure where you got the idea I didn't test out my old thermal paste, but the drop was 5-8°c under load compared to the Arctic MX-4 I replaced it with, it was used initially to test and make sure everything was contacting after the lapping as to not waste any CLU. It may only give you a couple degrees if you have a newer CPU with crappy thermal coumpund under the IHS limiting heat flow, but 5°+ is not uncommon among soldered IHS CPUs like mine, thus why I opted to lap it instead of just de-lidding.

Any chance a faulty PSU could be causing this?

Temperature difference between CLU and MX-4 TIM is about 2.3-3c, maybe 4c at most, not 5-8c. That's based on Tom's Hardware testing done 3 different ways

Yes I understand that, but what you don't seem to understand is every particular setup is different. Unless the tested out on a lapped soldered IHS and cooler then the results will vary, and again there are plenty of things like the crappy IHS paste that intel uses on all the new CPUs that will limit the CLUs performance. Even a delidded CPU will give varied results because soldering gives a much better connection from the die to the IHS than even CLU could ever achive (let alone the toothpaste intel uses), and because it then has a larger surface area on the lapped IHS vs just the smaller die, it's able to move the heat away more effectively.

But fine, lets have it your way and assume it doesn't even drop by a single degree, how exactly does that help my overheating situation? Are you trying to say my MX-4 that was clearly giving me worse temps will somehow help them now? I'm not trying to convice people to switch to CLU, just explaining my particular situation.

Everything was running great for about a week untill I added the new fans, didn't bump the cooler or anything, and as I said, have already double checked it's seated and properly applied. I wasn't even throttling to 3.0Ghz before lapping and while still on MX-4.

I've had some issues with my PSU connector's not seating properly, though that doesn't seem to be an issue right now, maybe it's just a bad connection somewhere and it's getting incorrect voltage or somthing? Messaged Corsair support about getting replacement cables, will report back to see if that helps.

Have you tried replacing the CLU with MS-4 sense the heating issued started with CLU?

all im aware of is how I delidded my q6600 back in the day
using heat to make the solder liquid and get the IHS off so you can run it without one



maybe you damaged the solder bonding under the IHS by heating up the LM on the IHS (if I understood you correctly)


if your confident about the TIM between the IHS and cooler, and the evenness off the IHS (well obviously) then that can be the only thing left, no?


why did it occur after adding 2 fans?
because the CLU on the IHS broke when hardened, you heated it up, but the solder under the IHS lost some contact when heated up?


if that's not it, what could possibly be left?

well everything is possible I guess, but a tool like HWiNFO should tell you if the CPU throttles because of temps at least

also I don't think you would suffer over voltage by a cable not plugged in correctly / being sub par quality

and a simple check with CPU-Z should tell you how much voltage is applied actually, well within reason of margins or error

When say I heat it up I'm not talking about taking a heat gun to it for several minutes, just 20-30 seconds on low with a hair dryer to reach gallium's melting point (bassically body temprature, same as if I heated it by just holding it in my hand for a few minutes). Otherwise the gallium stays solid at room temp and makes it 10× harder than it needs to be to apply and tack it to the copper. Doing this allowed me spread it out nicely and get a mirror like finish on both the IHS and heatsink. Also warmed it up when I seated it to keep the gallium melted to get a good bond and minimize the potenetial for any air pockets. It was running just fine for almost a week now, only started getting this issue after I went to add the new fans yesterday. I'll check voltages with HWinfo to see if there is anything abnormal. And yes, it's throttling 100% because of the temps, maxed out at 96°C on core 2 and 6 even when throttled down.

Yeah, figured I'd try it at this point, just cleaned it up and tried the MX-4, throttleing down ever harder to ~2.8GHz. Hopefully I have enough CLU left to re-apply :/

This is your CNPS10X Performa?
If so, my guess is you have a motherboard or CPU problem.

Indeed. Will see if the new PSU cables help and I'll try swaping in my i7-950 to see if it does any good.

X58 Rule! I'm still using 3 of these systems, a 920@3.8GHz, and two 980X's. Only complaints are high power use, old out of date architecture .. no high speed SATA, no USB 3, etc.

Yeah, got every single expansion other then the sandard pci which is being covered by my GPU filled. Usb 3.0 card, proper sata 3 card, 950 pro nvme m.2, etc...

My Sabertooth X58 board technically has "true" usb 3.0 and sata 3, but neither can run even close to what they should be and the marvell sata 3 controller is complete trash and somehow manages to get slower speeds in raid 0 than on a single disk.
