Recently after cleaning up my HD 7990 GPU and turning everything back on I have encountered a problem of having 1 of the 3 fans spinning at maximum speed just after turning on the computer, meanwhile the HWmonitor shows that the associated GPU core is at 30°C. First I thought there must be something with the 4 pin power connector, and I have disassembled it 4 times to 4 x check if there is something wrong with it, but no all 4 pins are intact, the connector's plastic frame is scratched because of trying to pull it off with a screwdriver but all the sockets are undamaged, the wires are all intact as well. Are there any solutions to this problem, because the fan sound is ANNOYING as hell, and the most optimal solution I have is to turn it off or to sell it and get myself another GPU, although this is a great one and it has served me with grace during the past 4 years! Looking forward to your solutions!
