Thermalright Ultima-90: Small Wonder?

Conclusion
The Thermalright Ultima-90 is a surprisingly good cooler, made even more attractive by the smaller size, lighter weight, and lower price tag than most of the top air coolers tested at AnandTech. In virtually every measurement the Ultima-90 was at least the equal of all the top-tier coolers, matching or outperforming the Tuniq 120, Thermalright Ultra-120, Scythe Infinity with push-pull fans, and the Scythe Ninja Plus B/OCZ Vindicator running a high output SilenX IXTREME fan.
At this point in time, Thermalright seems to have an excellent handle on how to design heatpipe towers that perform at the top of the performance charts. Now we can also add that they apparently know what to do to make a cooler smaller and lighter without giving up too much in performance. The Ultima-90 weighs only 460g, but it uses the same heatpipe setup as the much larger Ultra-120 eXtreme. That heatpipe arrangement of six staggered full loops creating twelve risers appears to be the key to the performance of both the eXtreme and this new Ultima-90.
The Ultima-90 is ideal wherever you want to use a high-performance cooler. Its smaller size and weight make it particularly well-suited to tight cases and motherboards with limited clearance around the CPU. It is also shorter than most top coolers, with a height of just 139mm. However, this is still not small enough for thin rack cases, a very small HTPC case, or a case that places the power supply above the CPU socket. The lower cost of the Ultima-90 will also be attractive to many buyers, with a retail price of $50 compared to other top coolers in the $65 to $80 range. You will still have to add a fan, but that can be as little as $5 to as much as $20 or more depending on your choice.
Thermalright advertises the Ultima-90 as a 90mm body with 120mm cooling power. That is certainly a fair description, because the Ultima-90 is designed to mount a 120mm or 92mm fan. It certainly performs best with a 120mm fan, but if you want to keep the cooler very compact it performs nearly as well with a quiet, high-output 92mm fan like the Panaflo H1A. If you choose the 92mm you will only give up a small amount of headroom at the top, and cooling in the overlap speeds is almost identical.
The Ultima-90 is not the best air cooler we have tested. That distinction still belongs to big brother Thermalright Ultra-120 eXtreme. Where the Ultima-90 carries our CPU to a stable 3.90 GHz, the eXtreme pushes it to 3.94 GHz. The eXtreme also manages a few degrees better cooling than the Ultima-90 at higher overclocks. However, in all other respects the performance of both coolers is all but the same. The Ultra-120 eXtreme is bigger, heavier and costs about $65 retail, where Ultima-90 costs about $50. However, the Ultra-120 eXtreme remains the better performer. You will need to decide which attributes are most important to you. Beyond the Ultra-120 eXtreme, we do not know of an air cooler that outperforms the Ultima-90. Several other top models match its performance, but they don't outperform it.
We asked in the beginning of this review if the smaller and lighter Thermalright Ultima-90 might be too compromised compared to other top coolers from Thermalright, Tuniq, Scythe, and others. After running it though our cooling tests we can only conclude that Thermalright made the right choices in the design of the Ultima-90 to make it the smallest and lightest air cooler we have tested that is still able to deliver top-of-the-line performance. At a price of $50 or less you even get some savings compared to the very best Ultra-120 eXtreme. We are pleased to have the smaller, lighter Thermalright Ultima-90 as a new choice for air cooling. Choice is good, even at the top, and the Ultima-90 will not disappoint you with its performance.

In these articles the Intel HSF is always classified as having the same noise level as the best coolers (and system-ps & no fans).
I have a X2 4600 however, and I hear the AM2 stock cooler at idle.
Does this mean that de Intel stock cooler is that much better than the AMD one, or is it just the measurement?
That is of real interest to me as I am looking to replace my cooler to make my pc more silent, not to oc it.

Early Intel 775 stock coolers were very noisy, but for the last year or so the Intel stock cooler is very quiet. That is further enhanced by the 4-pin fan connection that varies fan speed based on CPU temp and BIOS settings. Intel also uses a fan that is a standard 25mm thick.While I don't have measurements for you, the AMD fan is noisier to my ears. AMD does use heatpipes, but they also use a very thin fan that has to run higher rpm to move enough air for cooling.

For years Thermalright has delivered best in class performance with all of the products. No reason to expect any difference with the Small Wonder. Thermalright does good engineering and proves out their product instead of rushing some POS out the door as the trick-of-the week product. And with Thermalright you don't get some stupid shitze whisles and bells to sucker the clueless sheep into buying their products.Axbattler - Monday, August 20, 2007 - link
@ Wesley Fink: Can you please confirm that the height of the cooler with a 120mm fan attached is indeed shorter than the Ninja with a 120mm fan attached? I know that the Ninja is 150mm high, whereas the Ultima is 139mm, so I would expect, all things being equal that the Ultima requires less space than the Ninja. But a confirmation would be helpful as I've been looking for a cooler with comparable performance with the Ninja but a few (5-10mm) shorter.Wesley Fink - Monday, August 20, 2007 - link
1600 RPM is correct, and the chart is corrected.As for the Scythe Infinity, we can only report what we find, and others report what they find. You might compare test beds and methods for an explanation. The Infinity is deservedly loved by those whose primary goal is silence. That means the fan is relatively low output compared to coolers designed for overclocking as the primary goal.
We did find the Infinity reached 3.90 GHz at the top tier of our performance results when two fans were used in a push-pull arrangement. That is also included in our Scaling charts. As reported in our Infinity review the cooler can mount up to four fans.

Gents,I have been looking at the cooler market for about 2 or 3 months.. I was torn between the Tuniq 120, thermalright Ultra 120 and the Vigor Monsoon.. however each had a few things that i am a bit leary of. Mainly the weight and size issue. Currently I am running a thermaltake typhoon but am not happy with it. I have to go in every so often and adjust the screws holding it down as they appear to lossen over a short period of time. Based on your review of the thermals, i have just ordered the Ultima 90 and will drop you a line based on my results.
thanks!!

Been looking forward to an Anandtech review of this cooler for about three months now (since the first sneak peak review was seen on another forum). Glad to see this is indeed a pretty badass cooler! =)MercenaryForHire - Monday, August 20, 2007 - link
Something's not quite adding up there ...
