11700k. Any advice to get lower temps if possible?

[Garak]

Talk about buyers remorse with this CPU. Performance seems fine it doesn't seem to be throttling, but it's hot.

 

CPU: 11700k

Cooler: D15. Both fans.

Motherboard: Asus Tuf h570

Case: Lian Li Lancool II Mesh Performance.

Fans: Stock fans that came with the case. (2x 140mm intake. 1x 120mm exhaust)

 

Temps vary a lot. If my room is quite cool with window open I can get them down to around 40c idle.

When the room is hot idle temps are more like 50c+.

Cinebench multi core test is about 90c peak. (Noctua capped at 75% for noise. 100% doesn't seem to help though I've tried)

Cinebench single core test is about 65c peak.

Prime95 I can hit 100c.

 

Things I'm willing to do if it'll make a difference:

Change the case fans.

Add more fans.

 

What I would rather not have to do is buy an AIO, but if it was thought to make a significant difference... I would consider it.

 

Power limit settings are the 'asus stock'.

 

PL1 200w

PL2 250w

Tau duration 56 seconds.

 

I have tried using the intel stock settings which are

 

PL1 125w

PL2 250w

Tau duration 8 seconds (not entirely sure about this one can't remember)

 

Didn't seem much cooler and didn't maintain the boost. Haven't tried any other settings.

 

Would appreciate any and all advice short of selling it and buying AMD. (I'd consider it but it's just too much hassle)

Youre literally shortening the boost. Lower the overall wattage, not just the PL1. Also iirc, you could still downvolt even in H570 chipset with XTU, but please dont quote me on that.

[YoungBlade]

Have you made sure the mounting pressure is good? Those temps are really high, especially with a beast like the NH-D15. I was able to lower my temps a decent amount by just tightening down my cooler some more.

[SkilledRebuilds]

I thought stock TAU was still 56seconds..

8 seconds is a very very short boosting period..

 

As you never mentioned voltages...

Undervolt?

AIO isn't really going to help much. A 280mm like the Artic Liquid Freezer II would outperform the D15, but probably not by enough to matter all that much in the grand scheme. Going to something like a 360 or 420 would make a big difference, but I don't think there's room for that in that case. You might be able to get the same effect from like 2x240mm or 2x280mm rads, if the case has room for both, but then you're in to custom water cooling.

 

In short, you're pretty much done, unless you're ready to really kick things up a notch. Short of that, maybe adding more/better fans might help. Too many fans can be just as much of a hindrance to cooling, though, if they don't fit in with the general path of airflow through the case. You've still got headroom on the RPMs, so you may just need to accept more noise.

240 top (some say it can do 280 though) or 360 front according to the specs on the lian li website.

 

I had a feeling I should've got a bigger case, though. Ah well.

When you run cinebench what is the wattage used and clock speed according to HWinfo? My 11700f pulls 198 watts with no power limits, full speed 4.4ghz it goes up to 198 watts max temp of 67c using a corsair H115i elite cappelix (280mm aio)

Just throwing my #'s out there as a reference for ya

[Mister Woof]

I'd also +1 on making sure thermal paste application and mounting pressure is good

[xg32]

a couple of incremental things, noctua's fans can be at 100% and it's not audible, even though they are expensive, consider that to make the "tunnel" btwn the intake+d15+exhaust more powerful, kryonaut also makes about a 2C difference, i'd disregard prime95 temps and stick with cinebench and blender for normal use. tau should be as long as possible if not removed altogether.

 

i have these blasting at 100%, though the cost for 3 fans adds up, and a 360/420mm aio might make more of a difference, would not go from a d15 to a 280mm

[Garak]

They're definitely audible to me and far too loud at anything over 75%.

The case fans I can't run at over 50%, these in particular are extremely loud. (It also seems to make no difference running them higher anyway)

 

I've done as suggested repasted and remounted I got idle temps down maybe another 2c (unless it's an ambient temp drop) but peaks are much the same.

A 360 front rad may get the temps down a good amount. It's probably at least a better option than anything else you have right now, especially if you're not willing to accept more noise.

Missed this post. 230w. 4.6ghz. Whats your case and fans like? I suspect I'll end up getting an AIO at some point.

Love that scene. I think I'm due a rewatch.

[DarkSmith2]

i would delid -> rockit cool quicksilver to remove solder -> liquid metal -> sand IHS 

And with this you may get 7-10°C less.

 

To be fair switching from NH-D15 to the best 360mm aio possible will only do about 7°C less too.

With custom water you might be able to get 15°C lower temps... (with a Mo-Ra LUL)

 

Edit: BTW idle temps should never be used for comparison, the sensors in the boards are just not really made to be accurate when there is not enough load. Its also more of a "calculation/estimation" than an actual real measurement at that point.

I have a be quiet dx500 case, 3 140mm Corsair ml140 RGB pro fans as exhaust. Corsair h115i elite capellix set as intake.

I lowered the boost to 200w and it's around 80c, but as Gohard gets 67c with the same usage.

 

It still seems like I should have a bit lower temps. I'm tempted to try a different paste like grizzly and spread it on instead. Searching these forums I see people with the same cooler as me and lower temps it just seems a bit odd. Difficult to get a solid answer either way.

[Garak]

Just to let you know I got the temps down by about 8c by undervolting by 0.050. It'll do for now.

Did you double check the cooler's mounting pressure?
