>...but I have those temps on the AquaComputer block that I'm running now. Yeah we'll see about the VRM's. I'm measuring about 50C over ambient on the VRM's right now with the AC block.
+50C from ambient directly on one of the transistors? And I guess it at stock clocks (with boost only)? I think it's a good idea to use a backplate with pads (need to pick up thickness) for VRM zone + slow fan for cooling that backplate. Did it with GTX 580s and will repeat with Titans.
>I think adding MX2 to both sides of the thermal pad really helps (which this run doesn't have), but I need to get firm data on that to be honest.
EK wrote about this in manual. But is that OK if I have MX3? And is there any benefit? If it's only 1-2-3 degrees...

Sorry, I don`t understand - resistor on Titan`s PCB?
I only OC`ed this card under air (stock) in open case, fan was at 5000+ RPM and + two 120 mm side Slip Streams (1600 and 1900 RPM). Card consumption was up to 330W and back side of PCB (on the opposite side of VRM) was about 65-70C (infrared thermometer). Ambient ~24C.

>do NOT use pads on vram chips
block will not get enough contact to the gpu
But according Koolance manual, we must use them. That's strange. But also they wrote:
Multiple types of heat transfer pads are included with some Koolance blocks.
You might not require both (check the pad diagram). This is done because card
manufactures change the component height tolerance from time to time.
But it looks confusing, I prefer EK way
