As some of you may know, a few months back, I moved this motherboard to a new case and paired it with an i5-9400F CPU. The case I chose was a bit smaller and unable to accommodate the Noctua cooler that I had been using. But, I figured since the i5-9400F is locked and can't be overclocked, I thought that perhaps I can save a few bucks and an OEM Intel cooler would be enough... Boy was I wrong!

Screen Shot 2020-04-08 at 3.32.59 PM.png

When I tested Prime95, the CPU temps went all the way to 100C within 1.5 minutes!!! Fortunately, the built-in safety measures immediately started throttling the CPU. A Cinebench r20 run would see temps peak at 90C!! This was completely unacceptable.

The case I am now using can only accommodate CPU coolers 147mm or lower. Since it's a locked CPU, I didn't want to spend too much... So, was browsing around eBay and found the following.

Screen Shot 2020-04-08 at 3.24.47 PM.png

It's only 135mm tall. It has six heatpipes. It's cheap. The fan is only 92mm, but I'm working with fairly tight space constraints so it'll have to do. I decided to give it a shot...

I ended up replacing the 92mm fan with a cheap PWM fan too.

Screen Shot 2020-04-08 at 3.52.15 PM.png

Results:

Prime95
OEM Intel cooler hit 100C within 1.5 minutes and CPU stated to throttle immediately.
New 6 heatpipe tower cooler reached a stead 95C during a 20 minute run.

Cinebench r20
OEM Intel cooler maxed out at 90C.
New 6 heatpipe tower cooler maxed out at 82CC.

Subjective
OEM Intel cooler fan was constantly ramping up and down and made a slightly annoying "whirring" sound.
New 92mm PWM fan is nearly inaudible.


To be honest, I expected better results, but the new cooler is still a lot better than the OEM Intel one. I'll probably be deluding this CPU in the next few days...

Bit green of me here ... Can you use Liquid Metal when the heatpipes are 'bare' ? I've never used it but I know you do.

That cooler actually looks pretty impressive :thumbup: Bit surprised the temps are still going so high TBH. But are you OC-ing?

:)

Liquid metal can be used on copper and/or nickel. We just can't use it on aluminum.

Yeah. I also expected better results from the six heatpipes. But I think it's limited by it's physical size. It's actually still quite small. I also think that I just happened to end up with a pretty hot running i5-9400F...

No, I'm not overclocking. The "F" CPUs are locked and can not be overclocked.

it will be interesting how the temps will be after delidding...

Okay. I delidded my i5-9400F.

Results:

Prime95
OEM Intel cooler hit 100C within 1.5 minutes and CPU stated to throttle immediately.
New 6 heatpipe tower cooler reached a stead 95C during a 20 minute run.
Delidded CPU w/ 6 heatpipe tower cooler topped out at 77C during a 20 minute run.

Cinebench r20
OEM Intel cooler maxed out at 90C.
New 6 heatpipe tower cooler maxed out at 82CC.
Delidded CPU w/ 6 heatptpe tower cooler maxed out at 70C.

Subjective
OEM Intel cooler fan was constantly ramping up and down and made a slightly annoying "whirring" sound.
New 92mm PWM fan is nearly inaudible.
After delidding, the fan doesn't have to work as hard to maintain temps so it's even more quiet.


The Prime95 temps really show how much delidding helps and how bad the Intel TIM is. After delidding, the new 6 heatpipe cooler is finally performing at the level I expected. If I had an unlocked CPU, I would even be confident with a minor overclock.

Hey @pastrychef, I've been trying to upgrade to the latest EFI folder you posted from one that you helped me get working a few months ago from this comment. I've mapped my USB ports, and I think I've got everything working except shutdown at this point. I've attached my EFI folder which is nearly identical to your current one excluding my config.plist file. Any insight you can offer is greatly appreciated.

Please try with this config.plist.

Hi again @pastrychef after fixing the update I've experiencing more crashes and freezes than Mojave.
Currently at 10.15.4 and clover 5107

Attached are a couple of the crash logs.
Most recent one is when copying files between two external USB drives.

Any ideas what might be the issue?
