So I've built, I dunno, probably close to a dozen systems with Haswell / Devil's Canyon i7s, and lately I've been having trouble with chips that just run blazing hot under load.
The first of these chips was a 4770k that I had under an H100i that would spike up to 100c immediately under Prime95 small FFTs. I re-applied the thermal compound 3 times, tried all kinds of different settings for the cooler, including permanent 100% fan speed, nothing made a difference. I thought the cooler was at fault, bad pump or uneven coldplate or something, replaced it with a new one and same thing. In the end the only thing that worked was undervolting, which I've never had to do to get a chip to just run at stock speeds before.
I've got a 4790k now which is exhibiting similar behavior, and I'm pretty miffed. I'm not overclocking these suckers, just trying to get them to run at factory clocks without melting down. I've tried all kinds of different coolers and thermal compound, nothing seems to help.
Is undervolting the only solution short of delidding and thereby voiding the warranty? :/
