Lowering my GTX 780 SLI Idle Temps

post #1 of 3
Thread Starter 
So I bought two GTX 780 Superclocked Editions when they first came out. Now last week on a fresh install of Windows 8.1 they were idling at around 37 - 39c, which I was happy with. Now however my first card won't idle any cooler than 49c and my second lower than 45c. When I opened up PrecisionX I see that it won't stay downclocked for very long with spikes that keep raising temperatures. I've reinstalled both GeForce Drivers and PrecisionX and it doesn't help. I also went into nVIDIA Control Panel and made sure to set every startup program such as Razer Synapse and Rainmeter to Adaptive.

At this point the only thing I can think of is to go water cooling, which I don't want to because it'd have to be custom cooling and that would set me back too much or add extra cooling and came across this post http://forums.evga.com/tm.aspx?high=&m=1976578. Now, I really want to do something like this but I don't have a 3D Printer, nor am I really a DIY type of guy unless it's pretty easy. Any suggestions on what I can do? At this point all I can do is throw money at something in hopes of fixing it. I recently upgraded my case to a Corsair Obsidian 750D and filled it top to bottom with Noctua Fans. While not the best at pushing air, I have 2 140mm Intakes, 1 140mm Exhaust, 3 120mm Exhaust, and 2 120mm Intakes.

Weird that the temps suddenly went up. What I would do is to make a custom fan profile in Precision or Afterburner.
Get the Gelid GC-Extreme thermal paste, and take apart the gpu cooler and get it on instead. This will shave of some degrees both idle and load.

Was the temp increase a result of you changing case to something else, or was this done earlier?

Could be virus? i don't know, something similar happened when i had my first build. Is it like all of a sudden it spikes? Mine was because their was a false explorer.exe in the file systems, and when i force quit on it the GPU went back down, i eventually found the location of it and removed it.
