So I recently had to replace my old MSI x99a SLI krait motherboard, I got a Asus Rampage V edition 10, everything went fine installing I plugged in the 8 pin ATX power cable on the top as well as the extra 4 pin as I wasa having an issue and read somewhere that was a problem, anyway everything is up and running temps were a little high on my cpu on idle, fair enough as I probably put too much thermal paste, I cleaned it, cleaned the h110i contact area reapplied thermal paste (arctic silver 5) in a line rather than pea (cuz ive seen if done correctly the method doesnt matter too much) and re-seated it,I know theres a cure time of like 200 hours but ive never seen that matter and my idle temps are still too high I believe and I cant figure out whats wrong, when I orignally built this with the same parts on my msi board my idle temps were around 30C currently they around 50C, heres my specs.

i7-5930k 3.6
64 GB DDR4 2133MHZ
2x Geforce 1080ti FE in sli
H110i GT cpu cooler
Asus Rampage V edition 10
EVGA Supernova P2 1000w PSU

then an m.2 an ssd and an hdd of which I dotn think are relavent

just stress tested with prime 95 and at 100% load highest core temp was at 94C and lowest was 88C, I know thats normal (or maybe thats where prime 95 stops pushing when it sees those temps) but otherwise its idle is still much higher than my last mobo which went out on me 2 months ago now.

If your prime version is higher than 26.6 then don't use it on an Intel chip. It gives a more than impossible avx load which drastically messes with temps.

Did you reinstall Windows when you changed boards? If not that's likely cause an issue. If so then Windows is still probably updating pointless stuff and you're never actually at idle. 50c is definitely too high for idle but I suspect that is a falsehood reading.

I've not reinstalled windows yet, will I have to format my m.2 then as well? I only ask as I have some other files and stuff I'd want to pull then.

also using core temp for these readings and the cores are only at like 1% load or so, would they be that low if updating stuff?

Possibly. It doesn't take much to get s cpu out of idle mode. And with an reused os I'm sure all the energy saving stuff is turnned off since there are so many defualt/wrong/mixed up drivers. If your m2 has windows on it, and isn't partitioned yes you'll have to format it. If you're using it as a data drive then no

so after re installing windows and my mobo driver everything seemed fine (idle around 35-40), I went to work came back woke up my pc it would keep having to kick the fans on high with no apps running in the upper 70's, restart pc 70s temps on startup til they settle down to about 45-50 I start an app like league, without even playing just sitting at login and temps are like 55-60, this concerns me and confuses ambient temp is cool like...cooler than 25C I'm not sure if the mobo utilities could have anything to do with this but even though its safe operating temps it jsut bothers me it shouldnt be that high
