Guys, I just installed my GTX 970 (Gigabyte Gaming G1). Ambient is 74F. PSU fan now spins up under idle, even with the 120 mm fan and duct mod. So the mod really isn't worth it, unless you are running integrated graphics. I'll probably remove the duct and turn the PSU around so that it gets fresh air from outside the case.
WiSK, any news in regard to the replacement fan?
EDIT: Just another update - I've been using the machine for over an hour this morning. PSU fan hasn't come on yet. Ambient of 69F. Haven't taxed the GPU at all yet, whereas I did last night. Maybe the PSU just got significantly hotter due to the GPU loading (I was actually running Prime95 and Furmark last night, when the PSU fan wouldn't stop spinning at idle). So perhaps it'll just take longer for the duct mod to have an effect after gaming etc. Obviously I have more testing to do.
