just thought I should update from before,
I bought a new right fan from iFixIt (my last one completely died) and now I'm getting no throttling at all, GPU isn't going past 70 degrees (with 1035MHz OC) and CPU hasn't gone past 90 degrees (throttlestop with modifier locked to 24).
So, that was my solution.
Hi man, can you tell me if your fan was working at it's intended speed before the breakdown? and can you provide me with details on how&when did it throttle before the repair?
I finally got myself some screwdrivers and cleaned some dust from the macbook. The games are playable now at least. CPU throttles down in daytime but GPU stays locked at its intended clock rate now. At night times when it's cold, both the CPU and the GPU is working %100, only throttling in demanding situations for a split second. I'm thinking of cleaning the dust with a compressed air can (because there are no visible dust bunnies now. I think the nicotine may have formed a layer of residue over some airflow points.) and if that doesn't work replacing the thermal poo that apple provides.
