 About As Good As Air Gets
I bought this from FCPU before they even knew they were coming. I have a True Black on a QX6700 and can run p95 all day at 3.60Ghz (max heat test) With temps never above 71C. So, I was very excited when I heard the new i7 optimized "Rev. B" was shipping from Thermalright. I put this on my i7 920 Rev. D0, replacing a pretty capable Zalman CNPS9900LED. It was a bit tricky to get it situated on the cpu properly. Use patience and care...you will be rewarded.
With the Zal, I could only run p95 (max heat test) @ 3.60Ghz with any confidence. Core temps (Real Temp) were in the very high 80''s. Any more speed and the temps went into the 90''s...not good. After the proper installation of the new Rev. B Ultra-120 on my ASUS P6TDv2, using one Scythe "G" fan in "push", my temps @ 3.60Ghz dropped to the low-mid 70''s and I could run up to 4.20Ghz and stay below 90C running the max heat test in p95!!! That''s a pretty hefty improvement. I used the fan shroud that came with it to mount the Scythe and it''s whisper quiet at full tilt 1900rpm. This cooler works about 14C better under load than the Zalamn 9900 did, and it does it with less noise!
Motherboard clearance was a breeze and the new positive mounting bracket does a better job at keeping it where you put it. Height clearance could be an issue in some case models. Additionally, if you populate all your DIMM sockets as I do, you should check the installed clearance of the fan shroud. You may have to resort to clips. My clearance is less than 2mm, and I have to remove at least two DIMMS to make any adjustment on the fan shroud.
If you have an i7, don''t let the issues get in the way...BUY IT!!! It''s as close to water cooling performance as you can get, without the expense and hassle.

WOW!!! I Stand WAY Corrected!!!
In my first review of this, I trashed it because the base was out of flat...which it was...way out actually. After an elightening conversation with Thermalright (don''t ask for the number), I was anxious to either verify or debunk what I was told, so I installed this bad boy tonight on a QX6700 on an oldish ASUS P5W DH Dlx. It fit quite easily in my LL PC-60 Plus(B). Prior to this, I was using a Zalman CNPS9500AT which I had bought with the board along with the original Core2Duo E6700. That worked fine for that CPU, but then came a Q6700 and finally this QX6700. As you would expect, my O/C headroom was severely limited by the 9500. With the QX6700 and the 9500, I could only hit 3.25 reliably with idle temps in the mid 40''s and prime95 temps in the low-mid 80''s. Any more voltage and the pime95 temps were north of 85. Not good.
Now comes this True Black Ultra 120 (in 775 trim), and I can easily run 3.60ghz at 1.5v and idle in the mid 40''s and prime95 in the low 70''s!!! That''s a HUGE improvement, to say the least. No, I''m not seeing temps "below ambient"...and niether is anyone else on air. But this thing is ABSOLUTELY AMAZING and Thermalright''s astute technical dissertation is VERIFIED...IN SPADES!!!
For all you out there that just have to lap these to dead flat, don''t. Unless there is a MAJOR micro-finish issue with the base of your Thermalright, leave it alone. You''ll be glad you did. |

 Where''s the Quality Assurance???
Nice packaging. Excellent accessories. Looks great. The mating surface of the block was WAY out of flat. So much so that no hand lapping kit known to man would help it. I''d have to run this across a surface grinder to fix the bow (.015"-.030" side to side). No way did anybody look at this before it was packed. No excuse. I don''t care how good these things are when they are right, they are simply junk when they are wrong like this. Now, I''ve seen a couple of reviews of the Ultra 120 Extreme version where the reviewer gave it 4 or 5 stars, while stating that they had to spend a half a day lapping the surface to get it right. C''mon guys! I have two things to say about this. Just because someone is marketing lapping kits doesn''t mean that you should spend half a day using one. You should have better things to do with your time...if you don''t, get a life. Lastly, if you continue to fix this garbage instead of sending them back where they belong, Thermalright will continue to ship s**t. |
