    Hi started testing in ernest Prime95 - to ensure stability had it running for 15mins
    at 4.14 cpu stabilised at around 64-65 deg North/South bridge went from 36 -38 to
    52-54 deg. This is with the CPU cores at 100%...........if I use pc normally temps drop to mid 40's. Question:- What temp are the R2E bridges safe at? my concern is the board's cooling seems to rely on waste air blowing over heat sinks from a std CPU cooler.........my Mega Shadow with push pull fans just directs the warm air straight out the case......not over the sinks. My case has good cooling with 5 120mm fans........and appears to run very cool but there is little direct air movement over the bridge sinks.........I am keen not to fry my pc and need good reliability for next few years.

    Hope you can advise

    Usually the bridge chips are designed to withstand high temps, many board will go on for years and years even when the bridge chips are too hot to touch. That said its still good to keep the temps as low as possible, is there no where you can mount a fan to blow onto the bridge chips. Usually people have fans mounted at each end of the case so that air is stucked in on one side and blown out the other so you get a flow of air going through the case which will run over the bridge chips.

    Hi thx for replying...........things are a little tight...........but there is good airflow
    in case......but Megahelems is so huge it kinda disrupts airflow around n/s bridge.
    I will try and fix a couple of 40mm fans in..................directly over.

    Meanwhile, the mid 50's does drop to mid 40's when not running prime...........
    I'm sure this really stresses things.

    Thats actually pretty good, mine is at 40 at idle even with a fan directly on it! lol
