Hi, If i had thought about this when i was building this today i would have put my heat sensor for the fan controler on the chip case but i forgot so now im not sure where to put it physically.

The book says i can put it on the chip case or on the heat tubes but the heat tubes are round and i dont think it will stick very well. Can i put in on the manifold that connects the cooler to the chip case or do i have to put it on the tube itself.

The heat or temp sensor i guess you call it is just a small sensor in a long tube that is taped to the surface

See pic... thanks

In your opinion does that give you any assurance of how high the temps should be before you expect a failure point? Not that it will happen anytime soon but even the engineers at Intel have the thermal sensor for their processors mounted as close as possible to the CPU die to get as accurate a result as possible.

To be honest, your process is wrong and no it's not close enough.

You might to make yourself multiple cups of coffee and read through this.

You get best results by placing the heatsensor between the CPU's IHS(integrated heatspreader) and the cooler's plate. I would suggest avoiding the placement of the heatsensor on the tubes since you may not receive accurate temps.

I could be wrong though since I learned keeping the heat sensor as close as possible to the heat source.

Thanks so much, with it on the manifold i compared the temp of the cpu via EUFI and my Fan controller readout and there is about 6 max 11 deg c difference. Is that close enough?

Just checked it again, cpu from EUFI is 35 c and fan controller shows 24 c

OK thanks, i dont drink coffee but ill get a few cans of Coke Zero lol I was thinking that since the fan cooler temp is lower than the EUFI temp, this was a good thing. But rethinking that i can see a problem with that thought now.

So for example, if the CPU is actually 80 degrees and i have fan controllers set for 80 degrees, then the CPU would actually need to be 91 degrees before the fans kick into high gear. Yeah thats a problem. :( ugggg i dont want to have to take my cooler off :(

I will give that a read, thanks so much Lutfij :)
