ya should change back to stock heatsink and maybe try open the side casing as well. if ur temp drop significantly while side panel open, means ur air intake got problem

Hi,franky. I hv found ur CPU cooler fans hv opposite intake and exhaust . In normal , its shoud be CPU fans intake from front casing, button then exhaust hot air out to top and rear. U try chng it . Should be fine. All fans hv mark intake and exhaust marking like tick. If two intake →Cpu←Intake ≈ means only cool air in, buthot air can't 100% exhaust out. I suggest ur fans position like :

INTAKE: front, HDD bay, buttons,One of top(if got 2/3 slots 120mm or above ) near cpu top for intake.
EXHAUST : Rear(if can ,make two fans together for great exhaust cfm better ) ,Top (if got 2/3 slots ,one / two make to exhaust near 5.25 bay and moBo )
Hope can help to solve ur problems

And don forgot ur cpu i7 is over clock version 8n idle mode with ur cpu cooler should be around 39~43'c depending what and how many fans hv add in casing.

First : go to my computer→mouse right→manage/Properties for systems info.

Second : check ur all cable ,connector, pins, sata cables hv tights?

Third : check ur casing fans intake and exhaust,cpu cooler, fans got dusty ? Thermal paste check too.

If don't know or want fast to solve ,better go for shop or warranty(if items problems)

LOL...both fan is blowing into heatsink. No wonder la...

Totally agree What Kherel77 said and mark...

hello, anyone who could share a diagram of the push pull method? thanks in advance!

No need diagram...1 fan is push air into heatsink, other 1 is pull from heatsink. That all... Above pict shown is both push...& it was wrong.

your heat sink model is NH-U9B SE2.

It operates by push pull method. One fan push air into the heatsink, one pulls air out from heat sink.

now is all pushing air into the heat sink, causing turbulence inside the heatsink and trapped inside. hot air no where out.

flipping one of the fan around will drop the temp. depending where you wan the hot air goes,to the front or back.

hope this helps

Just turn around the fan on the left. This will turn the fan in out-take air. Which will blow the hot air out through the ventilation hole in your casing.

Bro, u clean up all thermal paste on processor and heatsink too. And just repaste a bit like 1 line on processor center enuf. Not much. And ur casing cables may use cable tiles it for better cool air intake to cool down ur system. Exhaut hot air also.

ouch ur temp heavy heating boss...well my noctua seem good to handle my i5 4670K..

Lol, our temp actually the same
My i5 clocked at 4.3Ghz, vcore 1.188 only but when run Prime95 could reach 95c
I re-seat my U12 few times yet the result still teh same
