Hello,

I have been logging my CPU temp now on HWINFO with my computer for about 20minutes on complete idle. It's sitting at a stable 59-60c.
My room temperatures are around 23-25c.

My build consists of,

I7 11700k
Noctua U12A with push/pull using 2x NF-A12x25
Corsair 4000d Airflow,
4 Corsair 120ll, 3 in the front, 1 in the back
2 Corsair 140ll, 2 top exhaust

I feel like this is way too hot seeing other post having varying temps from 30-60.
Do you have any suggestions that I can try to lower my cpu temp?

Thanks,
 
11700k + D15 it idles around 24 to 28c when fresh boot settles down, no overclock or core enhancements. Ambient temp around case is 19.2c sitting 3" off carpet floor in a cabinet with an exhaust fan built in the desk to remove air exhausted from case. 20c about a foot above desk, where's your case situated? Put a digital thermometer, even one to probe meat, and see what air temp is going through.

U12a should perform similarly to D15, 59c does seem high. If case placement isn't out of the ordinary like enclosed in a cabinet I'm thinking either the top case fans may be interrupting air flow or heatsink / paste application is not the best.

Try turn off both or at least one top fan closest to the middle of case. I run two top fans as well in Lian Li Mesh Performance case w/ only two front intake, so it might or might not be that but became aware later after my build top fans can interrupt air flow, just haven't done anything about it because haven't needed to.

If cooling hasn't improved id look at heatsink pressure applied by mounting screws. Not too much pressure has that can have the potential to bend pins but Noctua are pretty good. I turn tension screws until it hits maximum and then back half a turn, that's the pressure i go by.

If no improvement after checking heatsink or heatsink is already at enough pressure, just a half turn back from maximum, then try redo paste. Might be too much paste or the spread isn't centre. I like to do a rice grain size blob in middle and spread it manually with clear wrap on finger. Leave about a mm from edge for excess spread. This way you know paste won't spread in some other undesired direction because heatsink wasn't put on completely level. You using Noctua paste? I do.
