The i7-8700B on the Mac mini 2018 runs at 95,4% ✔️

I've done this to test the cpu:
-4 hours of prime95, 12Threads, 8k for max heat
-than Cinebench 15 -> 1211 pts    result "cold"->1269 pts

So you saying it reduces speed by 4.6% when its at max temp?

Hey all, I'm a new member here.

We've just bought a 2018 mac mini with a 3.2GHz 6-core i7, 32GB ram, 1TB SSD and Sonnet 650w egpu with a Vega 64. We're curious if we can meaningfully get any more performance from this mac mini before the new mac pro is released next year sometime. The computer is solely used for video editing work in Adobe and FCX.

Is there anything to be gained by reapplying thermal past or perhaps using Innovation Cooling's Graphite Thermal Paste?

We're not really expecting too much more but if there was something worthwhile we would get excited Smile

Thank you Smile

Seems like thermal paste change helps a lot on the Mac mini.

God I hate youtubers... so overly dramatic and such forced opinions, all done to drive engagement in the chase for the advertisers dollar. 
Maybe I should start a channel, “honest reviews from a non screechy anti drama perspective “. I doubt anyone would watch.

I agree with you about the YouTubers, @Eightarmedpet  "It throttled 200MHz down! Oh no there goes all my productivity!"

That being said, I do a little YT work as well. I made a video with my thoughts on it but to spare you I'll give the short version: the new Mac mini isn't meant for the "budget" crowd; it's really no longer the introductory Mac. Something that people like snazzylabs fail to grasp is that the Mac mini just wasn't selling well in the customer space but was doing very well in the enterprise, so Apple re-positioned it for that purpose. As someone who works in an enterprise environment I can tell you that we have no problem dropping $1500 per workstation & ordering 50 or 60 workstations at a time. No major enterprise will have an issue with an $800 workstation.

Sorry for the detour, back on topic: I know it's been discussed at length in other places but my 2012 Mac mini didn't have great thermal solution either. I used Noctua's NT-H1 thermal grease & dropped temperatures down from ~77C to ~65C. Bumping the CPU fan with TG Pro (which someone else mentioned here) up to 2200 RPM bring the temps down to 49C. If others are willing to try different thermal grease options we might could build a running thread of what temperature changes are.

@jim_survak Would love to see your video... sounds like our thoughts align.

I start discussing the Mac mini @ 39:50. It's about 20 minutes because I love the Mac mini & have a lot to say. And I think it needed explanation as to what the Mac mini was & now what it is.

I went ahead and added Thermal Grizzly liquid metal to my i7. I ran both CinebenchR15 and Blender (BMW) and screen recorded before and after. I used Intel Power Gadget to monitor temps and clock speed.  Peak temps were a few degrees cooler but nothing to OMG about, however, it did allow it to turbo boost a couple hundred MHz higher for longer resulting in a higher cinebench score and faster blender render times. I also saw a 200 point increase in Geekbench 3 breaking 5000/27000. All runs were with Mac fan control set to auto 50c fan ramp up. 
Cinebench before 1219cb @3.6ghz 97-100c
Cinebench after 1255 @ 3.8ghz 90-97c
Blender before 5:50 95-97c @ 3.5-3.6 ghz
Blender after 5:23 95-97c @ 3.8-3.9 ghz
Geekbench 3 before 4880/25497
Geekbench 3 after 5066/27383
Geekbench 4 before 5501/22279
Geekbench 4 after 5809/26632
