Fan Controller Temp Monitor - Reliable?

post #1 of 7
Thread Starter 
I have a 4 way temp monitor built into my Zalman ZM MFC2 fan controller. I wanted to ask some of you about placement of these sensors. I have this predetermined idea that they are useless, other than determining what your ambient temp or case temp is. When I stuck one on my CPU core, it showed 19C at full load compared to real temp showing 80C when I had my 2600k.

Should I place these anywhere that I cannot monitor through software? Will they be accurate? I have some idea's on what components they will help me monitor.

In between my mosfets and heatsink.
In between my memory heat spreader and memory chip.

Anything else you think these might read correctly? Will they even read these 2 area's well?

Unless I'm mistaken, they're just little thermocouples. They'll tell you the temp of wherever they are, so they need to be affixed to the surface of something if you want to know that specific component's reading, instead of the ambient air around it.

Why is it you're having trouble monitoring your core temps? Those should be from sensors on the motherboard itself :

ACC Enabled and 2 dormant cores are unlocked. My core temps read 0 on all software I have tried.

I worded my post very poorly. Let me clear up some confusion. I mentioned too much info, so I am going to edit the original post.

EDIT: On HW Monitor I do get a TMPIN 2 shows my socket temp I believe though.

Hmmm...I see your problem now. I have a bunch of ideas, but I don't want to recommend them for something as sensitive as a CPU. I doubt that sensor is going to cut it for those readings, and I'll leave the suggestions to someone who's dealt with this before.

Otherwise I'd recommend just affixing a K-type thermocouple between the heatsink and CPU, but DON'T do that, as it may cause a short or other massively devastating problems.

You could use the temp probes on the exhaust air of your GPU/CPU and setup the temp threshhold to control how fast your fans run.
When doing idle stuff like word processing or web surfing your case/rad fans run at low speed, and when you run games the fans spin up to max based on the temp of the exhaust air.

That is a good idea.

I do not believe I have any automatic functions like you describe with this fan controller. I will have to double check that though. It would be a nice feature to have.

I'm using the Scythe Kaze Fan Controller, and it does this well.
