I replaced the 7 deltas with gentle typhoons in order to make the rig suitable for in the house. I am currently running 2 1080ti founders editions, 2 1070ti founders editions and a 1070ti mini. Temps are 60 or below on all cards and the rig is pulling 880w at the wall. I am very happy with this setup now that the fans are quieter.
P.S. Octominer, please do not cut the cables on the deltas in future batches. I would have preferred to have the option of using pwm control rather than just a Molex connection. I would also recommend a grill above or below the psu mounting location to provide for better air flow to the psu.
How are the sound levels now with the gentle typhoon fans? Also how are the temps compared to the Deltas?
My house was 77F today because of the February heatwave in Boston. I don’t have a sound meter, but the GTs change the sound of the case from unbearable to gentle white noise (IMO). I previously used these GTs for a water cooled setup, so I knew that the noise wouldn’t bother me. Another anecdotal point to note is that the rig has been running in my dining room (right next to the kitchen) and I have not heard one complaint from my wife since I switched the fans. With the deltas running, my family wouldn’t eat in the kitchen till I shut it down. I have seen a 3-5 degree temperature difference between the fans with my setup of 2x 1080ti and 3x 1070ti. Once my server closet is finished, I will see whether an insulated wall makes the deltas bearable.
P.S. There are many reviews showing the performance vs sound characteristics of GTs. I wouldn’t say that they are the best, but they are consistently at the top in water-cooling because of their ability to move air through restricted spaces with relatively lower noise
