vmatrix Posted May 12, 2014 Share Posted May 12, 2014 Hello, I have searched the forum for another similar case, but I wasn't able to find anything. I have a GS800 80+ bronze PSU for 1 year now in my system. I am very pleased with it except for the noisy fan. When my system is idle the PSU fan is off, no problem there. The noise starts when my system is stressed. In that case the PSU fan spins up to full throttle and then after a minute or two it slows down to inaudible RPM. Even in that case the problem wouldn't be so disturbing but the thing is that after a couple of minutes the fan stops and then it starts again in full throttle and this cycle goes on and on. I already spoke with the reseller, which is one of the best here in Athens, Greece and they politely asked me to contact with your support department to find out if this is an RMA case or not. If this PSU has to go for replacement they can take it from here. Thank you very much for your time, Lucas PS The model on the label says 75-001183 Link to comment Share on other sites More sharing options...
Corsair Employees jonnyguru Posted May 12, 2014 Corsair Employees Share Posted May 12, 2014 I believe this was fixed in the GS 2013 Edition. They added time to the equation that previously only used a thermal profile. That said, if you only have one Radeon 6950, you should be know where near "stressing" the PSU out. Is the PSU getting proper air flow? Do you have it fan up or fan down in the bottom of that HAF922 of yours? What slot is the graphics card in and are there any other slots occupied with cards?

vmatrix Posted May 12, 2014 Author Share Posted May 12, 2014 -I have only one 6950 graphics card -the fan of the PSU is facing downwards so it sucks cold air from outside the case. -the graphics card is in the top PCI-E slot -no other cards are present inside the case -The case is equipped with one 20mm fan at the side, one 20mm fan at the front, 2 12mm fans at the top along with corsair h100i, and one 12mm fan at the rear. The only vacant fan slot is in the bottom, the airflow in the case is more that enough I believe. -Additionally, the computer never works in extremely high ambient temperature. When the temperature is above 30 degrees Celsius (above 86 Fahrenheit) an Air Condition is keeping the temperature at lower levels. The temperature of the hardware (cpu, motherboard, graphics card) is acceptable even in the summer (eg cpu stressed with occt or prime with avx enabled ranges 60-67 degrees Celsius).

vmatrix Posted May 12, 2014 Author Share Posted May 12, 2014 Is it normal that the psu fan starts at full throttle? The sound is almost as loud as that of a vacuum cleaner. Link to comment Share on other sites More sharing options...

Thank you for the quick reply Flip the PSU around. While the fan is sucking air in from the bottom, heat is rising into the PCB. Flip it fan up and the heat will have somewhere to go when it's in Zero RPM mode. Is it normal that the psu fan starts at full throttle? The sound is almost as loud as that of a vacuum cleaner. I don't believe so. Then again... depends on how hot the PCB is getting. Link to comment Share on other sites More sharing options...

Corsair Employees jonnyguru Posted May 13, 2014 Corsair Employees Share Posted May 13, 2014 Hmm.... Get an RMA for the PSU. Just doesn't sound normal. Link to comment Share on other sites More sharing options...
vmatrix Posted May 14, 2014 Author Share Posted May 14, 2014 can you help me locate the part number on my psu? I hope it is written somewhere on it because I have thrown away the box.. Link to comment Share on other sites More sharing options...
Corsair Employees jonnyguru Posted May 14, 2014 Corsair Employees Share Posted May 14, 2014 It's on the big spec label. Where it says "model:". The serial number is on that same label. Link to comment Share on other sites More sharing options...
