Hello all,
I have a cyber analysis workstation that I built from COTS hardware to analyze forensic data sets. Dual SLI on these MSI GTX 1070 Armor OC cards works within temp specs, but lacks performance needed. If I run four of these, they will rise well above temp limit of 65C to 90C in 5-10 minutes so I have to shut them down. GPU3 (aka 4 at the bottom) however remains unaffected, likely due to the bottom fan I thought would assist with upwards intake to upper fan for exhaust. The three front fans are intake in addition to the CPU cooler (as recommended). It's difficult to place the CPU cooler at the front due to controls on the main board (the standard buttons on the board and debug LED display are inaccessible by GPU3 aka 4 or bottom) and I don't think putting it at the top would help (as heat would rise into it).
As it stands now, I have noticed that if GPU0 (top) is activated with GPU3 (bottom), GPU3 remains within temp specs but GPU0 will begin to transfer heat to CPU above it (I noticed that CPU temps rise with GPU0). I really don't want to go water cooled on these, but will if I must. Most cyber forums where InfoSec pros did this used FE cards (which would exhaust from the PCI expansion slot instead of into the case (and surrounding cards). I thought the upwards motion of the bottom to the top, with the intake of the warmer CPU to cooler intake from the front, would result in a heat vortex rising from the top but clearly that isn't working. Note the bottom GPU temp, which is actually running at 90% remains quite cool. Am I doomed to the MSI Aero (FE type card) or Aero ITX perhaps better idea?
If anyone has any suggestions to check fans, the type or if you see a better thermodynamics that I could implement in the case - please feel free to suggest! Here's some images of the case from Spiceworks community below:
