mosfets are hot

When I run my 8RDA+ at 200FSB the mosfets(guess thats what they are) are blazing hot. I put some ramsinks on there to help but they aint much.

The ramsinks are blue and they get so hot they turn a light purple. Also are hot to the touch. But when I bump the FSB down to 166 they seem to run cooler. Would maybe adding better cooling to the north bridge help? My system is stable at 200FSB just stuff tends to run hotter.
 
This might be why 🙂 Mosfets are simple devices and they are not constantly on when in a staggered series such as this, they switch between them to balance the load. Most are designed for proper operation at up to about 90?C and their primary route of heat dissipation is through the thick copper layers in the motherboard. A quiet fan over them would help better than any heatsink glued to their plastic casing. Cooling the northbridge may absorb some heat that could potentially travel along the mobo towards the fets, but ultimately it wouldn't help much. I do know that the 8RDA boards have seriously hideous stock cooling on the northbridge though. It actually acts as an insulator rather than a heatsink as evidenced by this and this. In the least you should replace the stock TIM with some Ceramique or AS5. I would recommend a Zalman passive heatsink to go with it though.
 
those things just run hot... find another system and touch them as well.. hot.

i don't think cooling them will make a difference, but you can try, and let us know if it does! (seriously)
