there is 2 schools of thought about pump before or after your rad, one to keep the pump cool, one to keep the cpu cool, but realistically, it doesn't matter too much at all, the temp differance isn't going to be huge.

Just arrange it in the easiest way for tubing you can

hrmm.. well i will just measure the inline temp of the water goin into my pump.. if i think its too hot then ill switch it with the rad

I tried with my pump, which is much like a Eheim or any other magdrive. The impeller housing (where water flows) is pretty well insulated from the engine block. Actually there is no connection - hence the 'mag drive'.
The engine has its own housing and on good pumps such as Eheims this housing has fins - air cooled, baby.
So an inline pump wont add noticeable heat to the water. However if it's inside your case it will heat up the air quite a bit indeed ! (this is very noticeable with more powerful pumps)
Now, before or after the rad, i think if your flow is high enough it doesnt matter.

and as we all know plastic doesn't conduct heat very well at all. If you are really hung up about a pump dieing, just put it in a res, or aim a fan at it

in the bios on my Epox 8KHA+, there is an option to shutdown @ 60C, does anyone know if this actually works ?

one way to find out.....

just unplug your fan, and watch your temps rise, if they go above 60C, just plug it back in

If that epox is like the 8k7a I have the thermal probe isn't anywhere close to the CPU base. I dunno if I would try that or not...

I am thinking about desoldering the thermistor in the socket and putting a header on the backside. Then I could use a flat thermistor and get temps from the CPU top at least...
