It isn't bad enough the stock coolers where useally just enough to do the job.
Many still not properly adding TMI or themal grease to the bottom of the coolers in some cases none at all. Useing coolers that are smaller then they need to be or arent flat on the bottom, a a concave of convexness to them....
I mean this is the seconf nforce 2 boards out of 3 that have a problem. This is a biostar board and the chipset get up to 53C! CPU 56C+! 100% load of course resulting in problems dependinmg on room temp. I had asus nforce 2 board with the same problem...Again when I had a Asus kt400 board poor north bridge cooler ended up useing the one I pulled of the other asus... yet the a7n8x dulxe - e the stock cooler seemed ok
I not talking about the active cooler s but the passive heat sink only models. Not only do they not do thier job well enough they make a hot spot, radiateing heat like a little heater below your CPU causeing the CPU temps to get alot higher and the cooler to be far less effective. Over time it feels like I've been playing musical chairs with chipset heatsinks! LOL
Well I found replaceing you northbridge cooler drives down my temps adversly. I prefer useing the crystal orb.. (nickle plated copper)
A video card cooler round up many will find interesting...
(though thier quiet the last one i had was about 5500/6000 rpm, better then in the review)

Yes, there are more extreme like $30+ coolers but for $8 it does it job verry well not only that the low profile and airflow add to the cooling poential on your CPU's cooler and compleely remove the hot spot that caused so much trouble before:
Current CPU temp: 56C (Useing lapped / Stock AMD fan, 2400+ sempron)
Current Chipset temp: 53C
I'll post an update when my new order arrives to show you the difference... and I'll take before and after pics. I've allready added a TNT2 cooler to the southbridge the dropped it's temps from 49C @ 100% load to less then 35C!
