I have re-seated the cooler, re-applied the thermal paste and now it works as it should, with proper temps. Thanks everyone for the help

Hey everyone!
 

Last year I put a new pc upgrade together. The new config was:

i7-8700 (non-k) with cryorig m9i cooler
Gigabyte GTX 1080 Windforce
16GB 3200mhz g-skill ram
gigabyte z370 k3 mobo with latest bios
Zalman Z11 Plus case
Windows 10 Pro
2 HDD-s, one Sata SSD, one M.2 Sata ssd under CPU
XFX TS 550W Gold PSU

There is a friend of mine who always helps putting PC's together, and per his advice, worrying if the cooler would block ram sticks (it was a new build we wanted to be able to swap them out easily if they're faulty) we turned it facing the back of the case, thus the cooler fan was drawing air from that direction, opposite of what is commonly used. We took out the back fan, and put it on top of the case, right above the ram sticks, in exhaust mode. So basically my case had one factory intake fan at the front, in front of the hard drive bay, one outtake at top of the case. Everything looked fine, GPU was getting a little toasty but it's own cooler kept it within specs. CPU was actually well adjusted as far as temps go, only going to 77-80 C degrees when it was stress tested or on 100% load.

A week ago we decided to put things in proper order, turned the cpu cooler around the proper way, put one more fan in as outtake in the back. After all that the GPU was working with temps 6-10 C cooler already, but problem is, at the same time the CPU became that much hotter. It regularly hits 75+ C temps under only 60-70% load, with CPU-Z stress test going into 85-90 C territory, idle temps around 48-52 C, ambient temps in the room in summer 24+ C (living in Europe). I monitor temps with MSI afterburner and HWInfo64. I checked the bios , every fan is configured properly, speeds are fine. I took them out one by one, none of them made the CPU hotter, only cooler. I also checked voltages, but just as before (before turning the CPU cooler around again), it was hitting 1,25 V max, with auto voltages and 4.3 GHZ all core turbo, same as before.
One thing I want to note is that we didnt clean/swap the thermal paste (stock cryorig thermal paste) when turning the cooler around, I don't know if this could be the issue. I saw ample amounts both on the cooler's and cpu's surface and figured it should be fine. Or should we have cleaned/dusted the heatsink of the cooler off as well? At this point I'm frankly out of ideas, by all accounts the system should be all around cooler, yet the CPU is really really toasty.

Any help or advice is appreciated.

make sure the fan on the cooler is still blowing air towards the heatsink.

I checked it, it is blowing towards the heatsink. With the case side off temps have gone down by 5-6 C, but I don't want to have the side off for obvious reasons.

maybe put the top as intake?

Can't do that atm but wouldn't that ruin air-circulation? As far as I know hot air rises, so I would risk re-introducing hot air into the circulation. I also tried to stop it once with a gigabyte app while stress testing, to see if it's pulling air away from the CPU cooler, but as far as I could see there was no temperature difference. I did only try that once though so i might be wrong. What if I put it as an outtake in the other slot on top, to the left, above the cpu heatsink and near the rear fan?

hot air do rise, but it's nothing compared to the forces from the fan. If your fan cant even beat the force of hot air rising, it's broken.

 

I'd put both fans on the top as intake, so they blow to the CPU cooler. This case doesnt have much intake air through the front in the first place, and having that being so far away doesnt help.
