I bet it does. I also think that replacing stock RAM modules could be also a reason to void your warranty (if they find it out)

You don’t void the manufacturer warranty by replacing the RAM modules or reapplying the thermal paste on a Mac. The only scenario in which Apple can invalidate your warranty is when they can determine the changes you made to the system directly cause issues.

what has been the conclusion of this op? and this topic?

this is for that person that understands what this thread is about well

so it seems that the op thinking that the mini does not run 'optimally' due to the design of the fans?

and because of this, the mini has decreased speed. if the mini has decreased speed, what is the % decreased speed? 

because without knowing how much effect, or the impact the decreased speed from 'optimality' the decreased speed is having

then there's no meaningful results to be gain without knowing exactly how it much it matters or doesnt matter

anyhow what has been the conclusion of this op? and this topic?

could just put into a new, much cleaner post, and just link it here

Are you sure about the paste?

There is no conclusion, replace the thermal paste and just DIY a custom cooling solutions as shown, if you think it's needed.

The Mac mini 2018 cooling system is not suited to deal with the new i5 cpu's (old i7), without even mention new i7/i9, it is a fact!
It's only an issues if one use the machine to its full extent, for hard professional workloads.
Not an issue at all for customers that use it as classy furniture.

Nothing more, nothing less.

I know I’n new here so please bear with me. This is my 3rd Mac mini, the only real thread I have found online regarding the thermal design, and I know at some time this year, I’ll likely pick up an eGPU.

I knew of the thermal performance issues from reviews before I got my mini, and its configured with an i7 and a 2 TB SSD and gigabit NIC. I’ve deliberately set out to analyse and possibly fix the thermal solution that Apple has created for this machine. All of my work and notes will be free. Through the advent of 3D printing and open source CAD, I strongly feel a DIY aftermarket solution is viable. If anyone wishes to comment, or help me test, please contact me. My progresss will remain available here:

just a think out of the box idea:

can I DIY a water cooled mac mini with the settings like this?

the tube is thin enough to go though the gap of the air exhaust,

if you use egpu anyway,

there should be space on your desk to place a water cool reservoir and radiator too.

Anyone having problems with the built-in Aquantia 10GbE chip overheating in Windows 10 1903 (BootCamp)?
Mine disables itself after a few minutes of use. Event viewer shows:

Event ID: 19
Aquantia AQtion 10Gbit Network Adapter: Hardware overheat detected! Please power cycle the system.

A reboot doesn't do it, I have to power it off and on again to restore network connectivity.
Works fine in macOS however.

@squuiid Sorry to hear. I’d recommend running a utility like HWiNFO64 and see if you can keep a log of the 10GbE chipset. If it keeps overheating, contact Apple for repair/replacement.

@yesornofei That looks cool but will definitely be a maintenance nightmare. I would rather mod the 2018 Mac mini logic board to reside in a larger case with more airflow.

The workaround to this overheating is to use MacsFanControl app in macOS and set the fan speed to 2800rpm or so. The setting gets saved in SMC so when you go into BootCamp the fans kick in and keep things nice and cool, as they should do. Fortunately 2800rpm its barely audible.

Mesmerized by @megaseppl, both on the mac mini and his home automation. Respect!

I've done something similar with EurekaMaru, my mac mini. Resting on top of a Razer Core X (still waiting for it's graphics card what with the AMD releases and all), I designed and 3D printed a support for the machine, and a Core X matching 120mm fan support.

For those of you have a 3D printer, print this: M3 Mac Mini Mount by EidolonNight (print this if the whole model doesn't fit on the build plate of your printer)
and put a 140mm fan blowing upwards (with the bottom cap removed), it works great on mine and I am seeing roughly 6-10 C drop while playing GW2.

Macsfancontrol app works well for me. Thanks to @squuiid for the tip. Don't know who at Apple mandated a lazy cooling profile for the new Mini. Maybe that person esteems the silence of the 2013 cylinder Mac Pro as ideal. Ah, about that... actually, a melty-to-the-touch Mac Mini is somewhat alarming. Clearly more so than whisper fan noise. Mac Mini workstation, Braun kitchen appliance - two distinct apparatus here in 2019. Not much clamoring to converge the two. Just my input.   

Anyway, using the app, I re-profiled the Mini's internal fan to calmly ramp up gradually between 50 and 68 degrees Celsius. Instead of, you know, drunk-lurching into action around 99 degrees - the way Apple's fan profile does. (Not to point fingers or anything). Then to test the app's effectiveness - I ran a dozen YouTube K-Pop videos in 4K. IN CHROME. (Noooooo! Melty, melty. Aluminum enclosure-infused grilled cheese sandwich, anyone?)

So...what's the result? Ta-Da! Happy days! Now my beloved non-Braun, wholly-Apple, mini desktop product remains...slightly above room temperature. No matter how much K-Pop karaoke I throw at it. Okay, my Korean may not be the greatest, but the fan in the Mac Mini is now really effective. 

And yes, modifying the fan profile did increase performance in my typical work-flow. For example, I tested a four and a half minute CPU-only render in Maya 2019 for Mac, loading all 6 cores to 50-60%. According to Intel Power Gadget for Mac, my i5 processor now maintains a 3.9 GHz clock speed, even slightly above, throughout the render. I'm pretty sure that's as fast as any 8th generation i5 chip will go when utilizing all 6 cores. This is exciting. I had never seen my Mac Mini maintain that speed before. Now it does. 

With similar fan profiling, I wonder how fast the i7 Mini, and the i9 iMac can go?

What a wonderful topic!
i feel less alone now.
I bought a 2018 Mini one month ago.
I7, 512 Ssd,10 gig ethernet, 64 gig OWC ram ( installed by myself with iFixit tools )
3 screen with Akitio display port splitter, the third one plugged Hvmi. 
Run very well. 
Love the Mini since my late 2012 i7, 6 years old now, and running always fine despite the 16 gig ram limitation.
And yes, even in sleep mode, the beast is very hot.
I have a fan in front of it with external varispeed, but this stuff is so ugly :/
So I’v ordered a 140 mm Noctua fan, the Glory Blow Hole is stunning 😉 
Gonna mimick it ...

I did test the MacsFanControl , but even if i set the fan to constant 4400 rpm(max you can set),
reboot to carry the fan speed to bootcamp win 10(checked with my hand on the air exhaust),
the CPU temp are still in 4x C at idle, and 99 C soon when I run the benchmark in XTU app, still throttling a lot in temp.

P.S. I have the i7 mac mini 2018

To Sebastian Krampe : 
Thanx again for your post.
About the heat in sleep mode, I had power nap on. 
I did’nt check that, it was on by default since my 2018 have Mojave stock. 
On my 2012, Hi Sierra, it was off.
Althought there is a big usb 3 hub connected, now the temperature in sleep mode is very cool.

Since I’m building a Glory Blow stuff ( I’post pics when finish ) I wonder if it’s safe to take the plastic bottom away ?
Does it disturb the air flow design ?

Does the CPU still throttle with new thermal paste applied? 

 

Also, I've just found this: https://www.speed-designs.com/speed-mac-mini-cooling-base

Neat, but damn expensive (and doesn't say whether the fan is replaceable).

I've found a review:

The fan is replaceable, but it's 80mm and no dust filter and slippery plastic feet and the whole product looks kinda DIY raw - all in all I wouldn't pay 150$ for this, but the concept is pretty neat.

And then this: https://www.aliexpress.com/item/32963689468.html?spm=a2g0o.productlist.0.0.475c167ePo8u3i&algo_pvid=2ee1f144-d658-449f-86af-00e17b9aa882&algo_expid=2ee1f144-d658-449f-86af-00e17b9aa882-4&btsid=75746763-9dda-45bc-9971-9a137d24a177&ws_ab_test=searchweb0_0,searchweb201602_3,searchweb201603_52

Less elegant, but at least the price is right and it's 120mm, with double sided glue tape it even holds the mini without the base on, probably:D

The real thing would be an SMC controlled fan base, but I guess it's not possible for third parties, let alone for DIY-ers.

The Mac mini footprint is large enough to accommodate a 200mm cooling fan. You can get an adapter to power the fan through USB port. If you were to use an eGPU, you can get one large enough to fit the Mac mini inside or attach it outside.

I have a  Mac Mini  2018. I use it primarily for coding and especially for gaming in Windows. Usually when I'm gaming, the mini gets very hot when I touch it. I don't know the temps because I also don't know how to check it. Lol! I recently searched on Amazon a USB powered cooling fan:  https://www.amazon.com/AC-Infinity-MULTIFAN-Receiver-Playstation/dp/B00MWH4FL4/. I think this might help cool down the  Mac Mini . Has anyone tried this? I need to read your comments and suggestions before buying it. Thanks!

My cooling solution for MacMini 2018:

Three radiators (TOOGOO 150 x 60 x 25 mm from amazon.fr) held with elastic bands to a Mac mini, itself installed vertically. No paste used, the contact surface being huge I do not think it is needed.

I am not allowed to add pictures it seems.

EDIT: I am allowed, the option is just hidden:

Sorry for my late reply. I haven’t been here in a while.
It should be no problem to take the plastic bottom away. It‘s more a flow stopper. But I have never measured the difference with and without that plastic bottom.

I have the same or similar setup and do the same tasks as you and the best basic solution I've found via these forums is using a fan control app like MacsFanControl or Istat Menus and simply setting the fan to a constant RPM (2800 or so works for me), then restarting into Windows via system preferences/boot volume. As long as you don't shut the computer down, the fan will run at that speed until you either restart into Mac OS X and change it again or power off/shutdown. With this workaround, playing something like Witcher 3 on ultra settings only seems to heat the Mini a reasonable amount. I haven't tried any more robust cooling solution.

It is under the office table, it is not visible. 

That mod plus the Mac Fans Control and I think I am set for the normal use I give to the Mac mini, with seldom high intensity tasks while sorting out 50 MB NEF files from my Nikon Z 7.

Oh I see. I searched Macs Fan Control and there is a Windows version. My default OS to boot is Windows. But when running on Windows, the app only works on mac models that are not equipped with the modern T2 Chip. I guess I have to go with the Macs Fan Control workaround or try the Glory Blow Hole or something similar with either 140mm or 200mm fan. Thanks!
