Hi, i've been choosing on what heatsink i should buy for my intel processor. Then i came across the Thermalright Ultra-120. i know what fans ill be getting for it, so its not a problem.
theres 2 different kind of Ultra-120 and i was thinking what perform better in cooling. the Ultra-120 Extreme and the "True Black 120".
I read at the Thermalright website and it said the only difference in both coolers is that the True Black 120 came with the Chill Factor 2 (I Don't know much about Thermal Compound) and a extra set of fan wire clips for a push-pull, two fan installation.
It also said it perform the same in single fan mode. but ill be using 2.
Fragille is right; plus you get two fan mounting brackets for push-pull config if you want. I am not sure if the Extreme has the same pin configuration to allow push-pull with optional brackets; I know the TRUE does. But you could certainly fashion something of out zip ties. Overall, same cooler + extra accessories.
Btw, chillfactor is ok (I saw somewhere that CF2 may not be as good as the older one), but you're still better off using a different paste (Freeze, MX2, AS5 if you don't mind the cure period). And Ultra does have the fins for a two fan config, it would appear. You just need the accessory.
So, to sum it up, TRUE = Ultra Extreme + set of fan brackets + new thermal paste. Oh, and plus the cool black color, but how much are you willing to pay for appearance?
Also, I don't know what the other posters are talking about, it really doesn't have much to do with your question, but of all the sinks they mentioned Xigmatek is the best (read reviews, there are plenty).
FWIW, biggest factors, to me, should be mobo compatibility, weight, performance, price, in that order. Xigma is big, and the mounting brackets do not lay out as compactly as TR. Actually, the few coolers that outperform TR are bigger, IIRC. TR rocks the heatpipe design, they were one of the first to pioneer it.
