iMac 27" 2011 with Monterey
Hi
I knew that it's possible to install Os Monterey on iMac 27" 2011.
The way it's to change to video card original and use an Nvidia Quadro like K1000 , k3100 etc. and by using a special patch.
I suppose that we need to change the firmware or something else as to use this card on a Mac.
Anyone have information regarding this?
Many thanks!

Apple iMac A1418 Late 2013 - Fan run at max.
Hi there
An iMac A1418 late 2013 (but same problem on an A1419 too).
It works but very slow. Fan start to run after few second you turn on the iMac.
I've spoke with a friend in Apple, and he tell me about a sensor defective, but they usually replace the motherboard to fix the problem.
This iMac have no sensor (only one on the display), so I presume he means about a sensor on the motherboard.
Anyone have same problem? any idea about to solve?
Thanks and best regards.

Liquid Flux no clean
Hi
I've just finish my favorite Flux, I used Loctite MF210.
So my supplier is closed and I cannot find it in other place.
I ask you a suggestion to find a better Flux to use for rework.
I need a liquid flux no clean, no water based.
I use it for rework/reflow on laptop motherboard by use an infrared machine (Achi Pro).
I've got another good flux, a Solder Chemistry PRo, it's good but I need to clean it after rework, and in case of reflow the Bga don't move at temperature.
Can you help me on this?...
