Mach 2 gt temps

what CPU are you using? what mods have been done to the mach 2? pls go here to fill in your system specs so we can help you better

Ok updated that the mods i have been told are bigger condenser and desuperheater

many boards and chips have an issue reading below a certain temp, so you really cant go off that for sure. Put some load on it and see where it stands.

I just clocked it to 3ghz with 1.4 cpu core voltage the temps went from
-35° to -27° do you think that's normal with load?

Hard to say.

About the only way to know for sure what your temps are is to get a thermometer (forgot which the good ones are) and check it your self. Other then that its a trial and error thing and the installed temp sensors on the mach2 can be off by about 10-15 from what I understand.

fluke and uei themometers are the best

Look on ebay for uei dt150's, dt200's or maybe some of the 302's. Fluke has some good ones too, look for fluke 51's and fluke 52's.

Those will help you accurately measure temps, I got my old dt150 for $30.
