Looking for a good cpu heatsink for overclocking,.

The ThermalRight Ultra-120 is what I've been using the last couple of years on my CPUs. Very efficient so far and do a superb job.

[edit] Worth noting that you can use any good 120mm fan on it. I used a Scythe ultra-quiet model and have had great performance with it.

Go for 2 120mm fans:

It cools better because it's louder, AMIRITE?

+1 for the TRUE. Just get the standard version, don't worry about the 2kg hunk o copper, esp. if you are mounting it on a vertical motherboard. I used this for a couple of years before switching to a silent liquid setup. Not sure about the AMD chips, but this is a really well recgnised cooler for getting i7 920 chips to 4GHz without problems.

+1 For the TRUE as well from my corner. Also, the push/pull setup of 2 fans will not "double" your cooling power, it may not even have any real effect on your setup at all. I have nothing to back up this statement except for my good looks.

This is correct and hugely dependent on the system setup (fan type/speed/CFM, heat sink configuration, PC case/component airflow design, etc., etc. etc.)

http://en.wikipedia.org/wiki/Heat_si...oretical_model

Note especially the part about "When the air flow is not ducted, a certain percentage of air flow will bypass the heat sink. Flow bypass was found to increase with increasing fin density and clearance, while remaining relatively insensitive to inlet duct velocity."

More proof that certain heatsinks are designed for profit (i.e.: Oooohh...Shiny!) and not necessarily efficiency.

Because both fans are the same size and noise I doubt if you will hear any difference in overall loudness, unless the amplitude waves are synced which is almost impossible.

I would assume that a push pull of two fans would have more total cfm then a single fan. Would not two move more air past the fins then one?

I guess to many other factors are at work is see a resonable increase is cfm .... seems odd but I guess there is not a lot of difference in total cooling.

I guess it makes little difference but then again the cost of fans is nothing either.

I guess the one you are using the thermalright is just as good so whichever ....

Maybe the only reason to use 2 is that if one fails you are still ok ....
