l took your advice and ordered the Thermalright TR-TY143... Just out of interest I'd like to add that I think discussions about temperatures on this forum are a little over-hyped. 50C is a perfectly acceptable temperature for an asic to run at. Note that the menu shutdown temperature default is 80C. I worked for a computer manufacuturer and regularly changed ic's using hot-air guns where temperaturers attained hundreds of degrees C during the process and it never caused problems. You'd be surprised how much abuse ics can take. It's over-voltage kills them, not overheating.Hi mate, I take your point, but I think you've done the right thing. The asics in the S3s seem to be rather temperamental and someone posted a while back how just running without the case fitted was enough to 'x' out an asic that was distant from the inlet fan.
