What is the mobo you're running the FX8000 on? If it has a thick heatsink on the VRMs, incidental airflow wouldn't be much of a problem. This also depends if you're doing overclocking on that board+cpu. My current Crosshair V Formula-Z has a thick heatsink for the VRMs and NB, and I don't have any fans blowing on it, just the rear exhaust near it. I have my 8350 OC'ed to 5Ghz and my VRMs are hot but not cooking to say the least.

It's running on an M5A99FX Pro. The heatsinks are fairly big and the rear case fan should help keep things cool too.

I wouldn't worry too much about the VRMs overheating in your case(no pun intended). If you have good general airflow within your case, it shouldn't be too much of a problem. This also depends on your ambient temps and how much of an overclock you're pushing on your CPU.

I always thought the idea was to blow air on to the heat sink keep it cool. If the air around your processor is hotter than the processor its self, you should take it out of the oven XD.

Alright, I've been going through various official ATX design documents and it looks like the heatsink fans should push air in the direction of the heatsink (as suggested by others above) and that this is based on specific case thermal design guidelines. That is, that there is a side vent and/or duct that is located above the CPU area that would pull fresh air from directly outside of the case to the heatsink. In the case of the circular side vent with duct the air pulled in from the outside of the case would be even closer to the fan. So if someone has a case that doesn't have a side vent this idea is major fail. In that case, increasing the case front fan speed and using a larger CPU fan blowing out might be better. My Ultra Grid case has a side air duct and I'll have to try it once I find where I put it. Here's a picture of the duct: http://mail.ultraproducts.com/popupWin.php?noImg=10&sku=ULT33137&img_num=9

The replacement fan I used is thicker (25mm) and meaner looking than the stock AMD fan and I have the front case fan running around 1400 RPM so that's probably why pushing out was better. Using the AMD fan that way didn't make much of a difference. I guess you'll have to try both and see which works best for your system.

Now, keep in mind that there was also a crazy specification that didn't use a CPU fan at all but instead used the PSU fan to cool the CPU.
