80mm fan on a stock 2500+ heatink?

[The Green Bean]

thats what ive done. Is it a good idea? Ive done it with cable tiers. the thing s that the fan does not cover the entire heatsink. Some parts are bulging out. Should I replce with the stock fan? The heatsink has a copper layer underneath.

Ive lapped the heatsing and put artic silver 5 on it. I currently have 3 fans (hafta get another 80 mm exhaust). 1 120mm blowing onto the mainboard, and 2 80mms for exhaust and intake at the back and front respectively.

My temps are
CPU idle: 37. Load: 53
System idle :33 load: 35
Nbridge idle: 35 load: 43

Is the problem lack of exhaust, wrong fan on the heatsink or simply a bad heatsink? Ive heard ppl getting under 45load with similar setups.

its not that bulging out but, the heatsick doesnt seem to be hot. Even my GPU heatsink is hotter when runnig Prime95.

I have the stock HS as well and I used a 60mm to 80mm Fan adapter. I left the 60mm fan on, bolted the 80mm fan on top of that. I never go over 52C under load. I am going to try a Panaflo High 80mm fan by itself and see what I get. The 80mm fan is just a noname black one I threw in there. I am hoping for mid 40's under load to try some OC'ing on my Barton 2500. Good luck!

Some of the stock AMD heatsinks have round copper cores on them, with aluminum for the rest. Those models will cool really well. If you have one of the small ones though, with the copper base, and not very tall, I think your temps are about right.

Overall your temps are well within specs for the AMD cpus. So you don't really need to worry.

80mm on a 60mm heatsink bolted directly on may not be good because the dead spot in the middle of the fan is larger, and covers more of the heatsink so in the end less are may flow onto the heatsink. If you can attach it so the fan is above the heatsink a inch or two, that will help more air hit more surface area of the heatsnk.

What max temps should I reach?

And thnx...I think I have the latter heatsink of the 2.

I am getting 37 at idle and 44 at load now with Panaflo high fan.

The 2500+ retail HS is pretty good. The new fan overlap might even cool the chipset. Not a bad idea.
