looking at two coolers the Coolermaster Hyper TX3 $27.00 and the OCZ Vendetta 2 $48.00 for a PII 940BE 3.0.

I would say Vendetta 2 if only given those two choices.

Given a third I would say Coolermaster V8.

Tried both

Prefer Vendetta2. The surface is a bit mire unfinished but yet still cools better. Better results would be from even lapping the heatsink alone.
