I've been having some RAM issues and was borrowing roommates' PC for memtest.
After disabling fastboot and enabling boot from USB, I load up memtest and leave it running for four hours.
He comes back from work and wants to use his PC, so I pull the USB key and he reboots the PC.
ERROR: CPU Over Temperature!!!
(???)
so then he leaves for a movie with friends or something and left his windows logged in so that I could install Prime95 and stress test my RAM using a custom, high RAM load test. He has an i5-4690k.
I start up Prime95, watch task manager, and notice it's only running about 66%...hm..that's weird...whatever...in the mean time I download OpenHardwareMonitor and fire it up...hm that's weird, core 90C...the other temps under the core temp are all over the place-- some 50C, some 75C, one 100C. And there are 5 of them (temps), which doesn't make sense because quad core, used to seeing 1/core. Then again what do I konw, I'm AMD guy. Anyways, I put my hand in the case, touch the heatsink...weird...feels cold....
So I install HWInfo in case to double check....hm...yes...definitely 90C on the core...definitely thermally throttling...hm...wonder why
I shut it down and text him about it. I then realize I can't resist, that he's a complete noob for this mistake, and I remove the heatsink.
he didn't insert/lock the clips properly. Only the corner was making contact there....
what's crazy is he's been gaming on this PC for 3 months. The CPU was able to sustain about 50% load at 90C, and just cools off after about 10 seconds.

well, that's weird, memtest doesn't stress CPU at all...I've not seen that ... it doesn't do that....
