I've got 3x Temperature Probe controlled fans on my machine, with one Motherboard controlled one. The MoBo is older gen so has limited fan headers and only one with the 4 pin controller which is used by the one mobo controlled fan on an intake, with one TC fan supporting it and 2x TC fans drawing out...
Well, one of the TC fans on the outtake has stopped spinning - I've changed the plug to another header to see if it was that header and it's not spinning. It was the hardest working fan being one of 2 exhausts that the CPU cooler exhansted to, which is a bit of a bummer but these things happen.
So, i'm not up for playing the cables game with a replacement TC which may or may not live long enough, so am looking at getting 2x fans to replace it, (there is room for a second fan over the CPU cooler, it exhausts upwads through the top of the case) which would give me 3x exhaust with the last TC installed in the back of the case backing up the 2 fixed speeds in the roof.
So I was wondering: 2x constant low-speed 800RPM with a 37cfm draw each (giving a total draw of 74 cfm) or just go for full speed 1,350rpm constant fans with an advertised flow of 74 cfm each (combined 128 cmf) with the last temperature controlled fan doing whatever the hell it feels like on the back...
The advantage of the 800's is that they are super quiet and combined will have identical exhaust speed as the original TC.
The advantage of the 1,350's is that they are going to be double what was there originally.
I'd appreciate some opinions - the CPU fan at full speed would be going 2000RPM but I doubt it would go that much, but if it did would the 800's be a choke-point?
