I7 7700k idling 55 degrees Celsius and averaging 75-92 degrees on low load gaming

[tdm_rox]

Hi All,

I've read so many posts about this before but was wondering if any one could provide some insight for me anyway.

I have a 7700k which is idling at 55 degrees Celsius which seems super high and when running games like pubg or rainbow six siege it averages from around 75-92 degrees but usually sits around the 85 mark. I know 85 is semi-safe but it still boosts over 90 while playing games. I have set manual voltage to 1.2 down from 1.28 and I have also tried setting it to 1.15 but it made little difference.
I was running games a couple of weeks ago at around 55-65 degrees, then all of a sudden it was burning up - updated bios which fixed issue for a few weeks... now all of a sudden its happening again but not BIOS update is available..

I haven't tried re-applying thermal paste or resitting cpu/cooler for cpu yet but it seems like it wont fix the issue.

(Also this is all under 50% load... i get around 85 degrees at 35% load)

Current build:
I7 7700k at clock speed 4.2 with a voltage of 1.2 from mobo
H100i v2 Corsair water wooling (replaced stock fans with corsairs HD120 rgb fans used as exhaust on top of case)
1x HD120 corsair RGB fan in back of case as exhaust and front of case is 3x LL120 RGB corsair fans
Gigabyte z270x mobo
Gigabyte g1 gaming 1070 GPU
Typical sea gate 1T HDD and samsung 850 evo 500 gig SSD
2x 8 gig sticks of 3200 mhz g.skill trident RGB ram clocked at 3200 (enabled XMP profile)
Corsair 570x RGB gaming case

Reseat the cooler, redo the thermal paste, and make sure its not bad thermal paste because yes, thermal paste can go bad.

I re-applied thermal paste and replaced CPU cooler block, also switched the pump to the FAN_OPT header and running standard case fan in the CPU_FAN header.

It still idles high around 41-55 degrees but only reaching around 69/71 degrees while playing pubg

also a lot check the speed of your AIO pump, to ensure it is keeping up with the temp rise, if they are faulty or has a clog, it could be struggling to keep up.

Pump should be on FAN_CPU.
which Gigabyte z270x motherboard do you have, some have a special CPU_PUMP header just for AIO's

Those temps sound very high, my i8700k at 4.9hz idles around 23-25c and never gets above 65c under 100% load.
Which thermal paste are you using and how did you apply it. Imo less is more when using paste especially when using a good cooler that is ground flat from the factory.
