Blank screen and odd behavior of MacBook and iMacHi there, when I connect my display, it is recognized by iMac (2012) and Macbook Air, it shows up as LED Cinema Display,...
Antwort auf „Any potentail for upgrading GPU cooling?”I think 'thermal throttling' occures when the GPU reaches 80°C resulting in lower fps (i did quite some testing now). I would like to improve the cooling capabilities as well and thought of this: The foot/stance of the imac is an external heat sink of some kind. The exhaust is venting the hot air directly onto it. Maybe one could add a fin/heat dissipation thingy with thermal glue to it. Right above the hole for the power cable. Then use a quiet fan. Not sure hot to measure the success though. I guess a GPU temperature of 77° C with 300 less RPM on the main fan would be an improvement. It'd go from "noisy as !&&*" to "I can live with it".
