Thermalright HR-01 will work with Q6600 ?

Hey,

Anyone knows if the Thermalright HR-01 running passive with
a fanduct connect to the backside fan, will be enough to cool down
a Quad-Core Q6600 ?

No experience myself, but if it is ducted to a fan, I think it would work. TDP is 105W for reference.

Anyone else knows?

A Q6600 consumes less power than a Pentium D. It is not a question of whether the HR-01 will provide enough cooling (it will), but of how slow you can run the fan.

Well, if I use it with the fanduct connect to the backside fan,
it would be no problem, does it?
I have a Nexus backside fan, it is pretty silent around 800rpm.

Yes, ducting an HR-01 to an 800 RPM Nexus fan will be fine. You may be able to slow the fan down even more, depending on how low you want to keep your CPU temperatures. An average temperature of 65-70 is okay for C2Q processors. The maximum temperature should be kept below 80C. Throttling occurs around 85C.

Good to know.

I have the HR-01 + duct (collecting dust) and Q6600 B3. I'm going to try it tonight and report back the results. I will try both with and without the duct.

Last time I tried was with Pentium D 945 3.4Ghz (rated 95w). I didn't remember the temp at the time but I remembered I couldn't touch the heatsink for more than few seconds.

The HR-01 Plus is available now. You'll have to purchase the duct separately I believe. If an Ultra 120 with tight fins can passively cool my 95W TDP Opteron, a heatsink designed to be passive using the same number of heatpipes shouldn't have much trouble.

Ducts have worked for me too. The only complication I can imagine (if you use it in that p180case) is the ducted fun sucking in the heated air of the gpu.

Especially if it has the same number, or at least area, of cooling fins.

well, the HR-01 has fewer fins than an Ultra 120, and less surface area, but it cools better passively because it has more space between the fins. It's related to heat transfer and boundary layers and things I should understand better than I do, since I had the class less than a year ago.

I have the one that comes with the duct. It only has 4 pipes each side, not the newer one that has 6 pipes.

It is now sit on top of the Q6600 B3 (105watt). I ran nVidia stress test tool (2 hrs setting) and play game simultaneously (2 hrs). Nothing fancy.
I do not use ducting because the rear fan does align with the heatsink. The HR-01 is in passive mode. The heatsink is warm to the touch. Hmm my Patriot memory are generated more heat
