Hi guys,
here my two cents about cooling solution. I started to have some problem after display change. I bought for work a LG 34" ultrawide display with 3440x1440 resolution to replace my old 24" full hd display.
The "mini" manage it without problem (by DP at 50hz) even if officially it can't manage this resolution in technical spech. the only issue was the rising of the temperature. So i decided to start my intervention
This is a "work in progress" project.
Used materials for the first step:
- Mac mini 2012
- thermal paste Artic mx4
The original paste was dried an cracked, by the way, it has 8 years, so IMHO it's normal.
After replacement, immediately i found an improvement in termal management, but is still under pressure.
Second step:
remove the bottom cover and place the mini over a cheap cooling base for laptop (trust ziva).
Interesting results: during cinebench20, in both cases, it never throttle, but in standard configuration the internal fan runs at maximum speed (5500 rpm), and the temperature rise until 95-98°C.
Without bottom cover and the little wind, it was able to stay at 90 °C but with the fan at 4500-4800 rpm
WIth this good results, and seeing the "Speedo" professional solution, i decided to improve the fan power.
Third step, material used:
-USB fan of 140mm
-some rubber stoppers
I can't compare the results in cinebench 20 because now summer has come and in the room I have 29 °C (instead 20-22).
By the way, with this solution, I can hold the CPU at 47°C with web browsing (firefox), Whatsapp desktop, email (thunderbird). The fan stay at minimum rpm (1800).
fans control has been set to start at 65°c with a maximum target at 90° (CPU PECI)
Currently, I'm quite satisfied, but I still have the last step to improve: built a kind of "case" to hide the fan that looks like a base for mini. I'm also thinking about whether to include a small USB port hub and SD card reader in it so that they are available in front.
Stay tuned for the news.
