GPU Block Heat Sensor Placement ??

post #1 of 10
Thread Starter 
Hi all!
At this point I only have my case and my mobo in hand, still shopping/ordering the rest.

Never the less, I was reading my mobo literature; it's a Maximux V Extreme.

With it, comes a heat sensor (the tape wire kind covered with a plastic film).
That sensor is used to assist 3 of the 4 pin PWM headers. (this mobo has 8 PMW headers btw)

I want to use these headers to control my GPU loop's fans.

My CPU PWM header will control the CPU loop's fans while the FAN PMW headers will control the GPU loop's fans.

But where am I supposed to stick that sensor? I sure can't wedge it between the GPU and water block.

So am I supposed to somehow glue it to the water block near the GPU?
I'm guessing the temps readings won't be all that accurate if I do that.

Where should I shove that sensor? ...........(hmmmm, maybe I should re-phrase that!

Cheers,
Pepelapiu

On the GPU block and zero the sensor

^This. The GPU block should get fairly warm (especially a full copper block).
 
Fun inside...

A really adventurous soul would cut a channel in the heat spreader on the GPU just deep and wide enough for the thermocouple to fit in.

Zero the sensor? What do you mean?
It's just a wire with a flat end to it.

I am not going to carve up a 700$ card's GPU...... unless you let me practice on your vid card first.
However, you might be on to something ..... I could carve up a small relief into the water block where it makes contact with the GPU. Even if it is a little too deep, I'll just grease up any void remaining.

But I haven't figured out what controls which header so far. It's obvious the CPU header is regulated by the CPU temp but I'm not sure which header is regulated by that wired heat sensor I got.

The Maximus V sure is extreme in a lot of ways.

Let's say your GPU is at 30*C, you place the sensor on the block, it reports 20*C, a 10*C difference right? Zeroing means adjusting the sensor(via the motherboard software, most decent software allows this) so the difference is zero

You can use a pwm fan and speedfan or similar software to find what header is linked to what sensor by connectig the fan to each header and changing the pwm speed
