High Idle Temps

[SugaSt]

Two days ago, I finished the following build.  I believe the idle temps are higher than usual considering my cooling equipment.  Should I recalibrate my expectations are should I make any tweaks to my setup?  I've attached my build specs.  Thanks

What's the temps?

 

What do you use for measuring?

 

Can you post full specs and maybe some screenshots (of the "high temps") as I don't think ima dl a random pdf just to see that information (sorry)

you did not forget cooling past? (happens more than you think)

[manikyath]

how about you post about your problem, instead of posting about your PDF.

Idle temps don't mean much, what are the temps under load ?

Anyway a 240mm AIO isn't very good on a 265K, and it will throttle if you push it at 250W+

Pea sized doesn't sound right on such an elongated cpu. 

Safer to spread paste over the whole surface with a credit card.

Also I think a contact frame is still recommended for that socket.

I did limit the ratios in my system due to thermal limitations.

1286rpm at idle sounds excessive.

3812rpm at idle sounds very excessive.

(I use FanControl to manage my fans)

I apoligize for the PDF not attaching.  I'm a newbie to the site!  Here are the specs:

 

·         ASUS TUF Gaming Z890-Plus WiFi

·         Intel Core Ultra 7 265K

·         MSI Ventus GeForce RTX 5060 Ti 16GB GDDR7

·         Patriot Viper Venom 64GB (2x32GB)

·         MSI MAG Coreliquid A13 240

·         Samsung 990 Pro 2TB Gen4 M.2 2280

·         Samsung HD 103Sj 1TB (2)

·         Fractal Define R6

·         Corsair RM850e

·         Windows 11 Pro

 

 

At idle:

·         CPU Fan: 1286 RPM

·         3 chasis Fans (1 rear, 2 front): 690, 698, 720 RPM

·         AIO Pump (radiator top mount): 3813 RPM

·         CPU temp: 47C, MB temp: 32C

·         Ambient Room temp 23C

 

Notes :

·         I have all settings in Bios set to default, no overclocking, etc

·         I used pea sized ARCTIC MX-6thermal paste on CPU

·         I’m using the mesh, ventilated top panel on the case, not the solid insulated top.

I didn't know fans could hit 3800 RPM

Must be noisy at idle.

While 47C is ok (what's your load temp?), I'd expect less.

Our 13700 (iBuyPower) idles at 35C and runs perfectly silent, wouldn't expect a core ultra to run hotter.

Buuuut if load temps are ok it's nothing to worry about.

That 3800 RPM though, that must sound like a jet engine...

Used HWinfo64 for those numbers?
