13700KF Temps

I recently built a Z790 / 13700KF setup (air cooled with a DeepCool AK620). I know these chips run hot, so I've been looking at undervolting it.

At stock voltages, it hits 100C in 5-10 seconds when running Cinebench multi core. Undervolting by 0.065v or so (adaptive) helps a little, in that it takes maybe 30 secs longer to hit 100C, but it still hits 100C and then pretty much stays there. I've tried undervolting further, right down to -0.16v but, although it's stable, it doesn't seem to bring temps down any further.

In the videos I've watched on YT, they're typically bringing their temps down in Cinebench by 5C or more, so I'm not sure what I'm missing really. I know an air cooler isn't going to work miracles with these CPUs, but the DeepCool had decent reviews. I've tried reapplying thermal paste, which helped marginally but again not significantly.

Appreciate any help :)

cheers

Intel put out a lot heat that’s for sure, but Intel don’t normally it 100c in 5 seconds. I think your cooling could be the issue TBH.

What case are you using and what are the system specs?
 
Being an Asus board the multi core enchantment is likely to be enabled and it will suck as many volts as it can. Disable that to set the limits... Secondly if you modify the AC/DC load lines you will bring the temps down... Search the forum I have mentioned the guide here before

Sorry, would've helped wouldn't it. Case is a fairly cheap Falcon GameMax midi tower, which I don't think gives the best airflow, especially with my crappy cable management. I tried removing the side panel of the case, and it helped slightly - managed to do a complete Cinebench multi run without hitting 100C - only 98C :D

Other specs are 3080FE, DDR5 6400MHz RAM. Mobo is an MSI Pro Z790.

Thanks. It's actually an MSI board (prefer Asus as not had good experiences with MSI in recent years, but Asus Z790s were too £££). I'll check BIOS for a comparable setting though.

Install HWINFO or something similar to get an idea of how many watts the cpu is pulling under load.

Also worth considering a contact frame. May help with temps.

Have been running HWMonitor anyway, while testing undervolts in Intel XTU. Peak power draw looks to be about 243W.

Edit: Will look into contact frames too. Thanks!

Side shot of case, for what it's worth:

Apologies... Not sure why i thought it was a Asus board... Bad habit. I'm sure the settings are similar though. I have a 13900k and af2 360 cooler. With a few tweaks it only pulls around 225w in cb23 and goes to around 82 degrees.

Have you exhaust fans in the roof of the case? Have you read reviews on that cooler to see if it's adequate? I have no experience with them
 
Might be a bit of a pain but could be worth taking the cooler off and seeing how the paste distributed across the coldplate, if its making proper contact etc.

Funnily enough, I actually did that earlier. It looked OK, but to be sure I removed all the (Deepcool) paste and stuck some MX4 on there. The original paste looked like it was fairly evenly spread though.

No worries, I found the equivalent MSI setting in BIOS (it's called Turbo Enhanced) so changed it from Auto to Disabled. Didn't seem to reduce temps noticeably although Cinebench score was slightly better (~ 30,600).

No fans in the top of the case, but there is a decent sized vent:



I'm pretty sure the cooler is up to the job, I went with this recent review which said it's "one of the best performing air coolers right now".

What are the PL1 and 2 numbers? Set them to 253.

Yeah, that system is going to need quite a lot of attending too in cooling terms. Turning the front fan speed up and adding an exhaust fan would be a good start. I would be tempted to fit a 240mm AIO in the front or go custom loop.

Thanks, will try that. They're both showing as 'unlimited' in HWInfo64.

Yeah, they should not. MSI bios will probably show some dumb numbers.

my MSI bios asked what type of cooler i have, and sets 4000w(unlimited) if you have a water cooler.

in bios on the EZ screen press F7 if you see the advanced menu. bottom left it was say cooler settings.
if all you do is game pick box cooler, my CPU boosts as normal with this setting under gaming and CB r23 loads. if you want to OC a little pick tower cooler.

You need a rear exhaust fan. move one of the front fans to the rear for now

The official specs are 253w and those should ideally be set unless you have full blown water cooling. Does not matter if you choose their water cooling or tower cooling. If the correct settings are applied with box cooler, then that is cool.

if your running a BOX cooler intel recommend 125w the power the CPU is designed to run at, if you have better cooling(tower) the cpu will boost and use upto 253w
if you have very good cooling say a 360mm AIO the bios will set 4069w the MAX rated power, this was the same with EVERY cpu all the way back to 1150(that i know of)


it just lets the CPU boost higher for longer, or unlocks overclocking if you want to... but this is cooler dependent
