It is a thermistor type from Cooler Master. It is small.
When I say on the die I am NOT talking about on the surface that will interfere with heat transfer but on the side of the raised portion of the CPU.
Taking your CPU's tempeature is like taking a person's. It more accurate to place the probe "under" it so to speak, but usually a whole lot easier to place it elsewhere.
I suggest you read this whole thread before anwsering.
I did read the whole thread. So you didn't like my comparison, that doesn't make it false.
It is still more accurate to measure the cpu's temperature from under it as opposed to mounting the probe on the water block for several reasons. But it's more difficult to place the probe there so most people place it on the water block. It's a simple point. Not very difficult to understand. I'm not saying to measure it between the waterblock and the cpu, but under the cpu. There are probes designed to do just that. I have one on my machine. It's a pain to install, and would have been much easier to put it elsewhere.
So I suggest you step back and understand what I was saying before you start taking pot shots at me.
You can disagree with me that my point is not valid if you want. If that is the case then it would have been nice to state it in the manner. Since you can't possibly know if I read everyone's post or not, you really shouldn't speak to that point without finding out first.
