Hi,
recent new build, i9 13900K, MSI MAG Tomahwk WiFi DDR5, MSI MAG CORELIQUID 360R V2.

running fine for a few weeks now, no temps above 70C under load (I do a lot of Audio).
I updated windows yesterday then noticed the fans were on high. looking at the temps, package temps hitting 100C and all P and e cores as well, was fine previously.

i did notice win search indexer doing its thing causing 100% cpu in task manager, stopping this brought all the temps down to 50-60C, but obviously indexer starts up again and temps go high again.
all temps reported 96-100C when running cinebench and indexer running, but with indexer stopped temps running 60-74C with cinebench.

ive got good airflow, no dust as recent new build. all drivers and firmware up to date.
Installed a contact plate today, thermal paste was in good contact with cooler and CPU previously looking at it.
Im not doing any overclocking.

any ideas on what may be happening, there is no instability when using the computer for audio, no stuttering, etc and no shutting down.
appreciate any help
thanks
tony

ive done that, done a complete virus/malware scan at boot.., now there seems to be a WMI provider host and system hogging things... keeping temps up.
shame I dont have another cooler I could use to see if its that, I know the MSI had a recall, V1 i think, mine is the V2 and checking on their website its not a recall device.
didnt have this problem till the win 11 latest update, can i roll back?
thanks

thanks everyone, seems to have settled down, normal temps now, not sure why except for turning off indexing and doing a boot virus scan, found a few files it didnt like but not convinced these were malware, one was UVI workstation....
will try and update nvidia driver as well...

when running cinebench, what temps would you expect to see for multi and single core tests?

hi, i did a benchmark 26+K multi, latest win 11 build 22H i think it was, im thinking cooler now as soon as i do anything, temps go up to 100C, but idle 50-65.
Its only been since I updatedwin11, never heard the fans come on at all except when room was baking hot, was silent most of the time.
 
HI, im away from home at the moment, but was thining of trying the thermalrite silent assasin as an alternative when i get home to see if it the AIO that is the problem. IS this ok for the 13900K? gets some good reviews, or should I stick with the arctic AIO cooler?
any other recommendations appreciated.

thanks
Tony
 
hi McNumpty2323,
the MSi AIO i have is new, so should not really be having these problems, wanted a cheaper alterantive to see if it is the cooler causing the high temps or something else.. jsut wanted to make sure it was ok.
but if there is a definite AIO or AIR cooler for the 13900K.
the case does have good clearance and airflow, never been problem before the latest win update.
 
Sorted, got me an Arctic Freezer II 360 A-RGB, static temps at 35-40, but still high under load (cinebench multi) at mid 90's up to 100C, is this normal. mid 50's in single processor mode.
Must have been a faulty pump on previous cooler (was new so getting a refund), failed at same time as win update, co-incidence?

Have an interesting problem now, all the ARGB fans on the cooler are connected in series, all to pump fan header (and tried CPU,header on motherboard) all to same ARGB header but all bar one of them show different colours compared to my other fans connected. any ideas on this one? MSI board so mystic light being used in rainbow mode, if i set 1 colour they are all the same colour then.

thanks for all the help everyone

Ive undervolted so keeping temps a little lower @ low 80's now with a 70uv undervolt. it is warm in the room with the sun etc.

Fan configuration of the 3 AIO cooler fans are set to intake on front of case over radiator, 1x 120mm in at rear and 2x 120mm out/exhaust at top with some space around them for extra exhaust, radiator would not fit as exhaust at top ;-( .

weird its only the 'rainbow' colour scheme that the fans are out, probably software although just updated to the latest version, still the same but solved with a little cable revamp.. ;-)
