Macs Fan Control temps are all normal ( 35-40˚C) but the right fan is stuck at 8800~ rpm when it should have been 6864 rpm...

I already bought the missing parts but the problem is I need quite a bit of skill as well as a hot air workstation. Hopefully someone would be able to fix theirs using the info below: Here is the fan control circuit on the board (It’s missing a MOSFET-[Part#Q6050] and a Resistor-[Part#R6051]) Here’s the location of the parts on the board Here’s the diagram for the fan control circuit Finally, here’s the parts that you need (They’re really tiny haha)

Hi! I have the same issue and I found out one of my transistors, more specifically Q6050 was mising from my board. It was yanked out most probably during reassembly. (Oh yeah, and a resistor too) As you can see the trio of black resistors and the transistor in between should be complete each fan but the one at the bottom has missing parts. The transistor is the black block while the resistors are the silver ones with a black middle. I've ordered these parts online and I'll get back if it fixes the issue.

Hi! Same problem here. Happened 6 months out of warranty. Unfortunately, no Apple employee would acknowledge this.
