Hey guys, I've just instaled a new Thermalright Ultra-120 cooler on my processor. I want to share my experience with you guys, since I've read a lot of bad topic about this cooler, let me make a positive one!!!
Most of the bad topics I've read, people are getting hight temps because their Ultra-120 didn't have a flat surface, so the thermal paste did not spread like it should has.
Mine is totally flat, and let see how this things cool down a CPU.
First, I've bought this cooler because I overclocked my system, and the temperature was around 50 celcius at idle and 60 celcius at 100% cpu used. The stock fan was getting very noisy and I could'nt sleep anymore.
Here's my system rigs:
AMD Athlon64 X2 4400+ socket 939 @ FX-60
DFI LANPARTY UT nF4 Ultra-D
2GB OCZ PC4800 Elite Edition
Antec P180 SPCR black first version
4x Scythe SFF21E 120mm fans
First thing you need to known, is when you overclock an X2 CPU, once you give more than 1.5volt at the Vcore, the temperature of both core goes insane!!!
So here I go, I install this monster heatsink on my socket. (Nota
: you need a Thermalright K8 Backplate to install this on any DFI motherboard, sold separately.)(Nota2
:Compatible AM2 socket, but mounting equipment sold separately).
Once installed, I installed my 4 sticks of RAM. A lot of huge heatsink like that, give you an hard time installing DIMM modules after having installed them. But this heatsink is different. I had no trouble at all installing my DIMM even after the cooler was installed.
See pictures below, you have plenty of space, even if your RAM has heatspreader.

Also, It will leave just enough space to intall the video card in the first PCI-Express 16 slot.(Nota
: If you use a big VGA cooler, like the Thermalright HR-03 with the heatsink toward the CPU socket, it is not going to fit.

Ok, let's start the machine without installing a fan on this things. But still having the two rear and top fans installed in the P180.
Temperature was 50 at idle, it droped at 37 celcius. Not bad at all, but let's test it when the two core are used. I ran two sessions of Prime95, one on each core. Temperature rised instead to 62 celcius and might have got even further, but I stopped Prime95 before my CPU explode, since the maximum temps on an X2 is 65 celcius loll.
Ok so then this heatsink isn't good at all if you want to use it passively, when your system is overclocked. If your system isn't overclocked, I'm sure you should'nt have any problems. My CPU stock voltage is 1.30v, and to overclock it I had to use 1.59v. Like I mentionned earlier, X2's temps goes insane when you put more than 1.50v at the Vcore.
I havn't tested the system at stock speed passively nor actively cooled, I did not see any interest, because of this last fact.
So now let's install a Scythe SFF21E fan on this heatsink, which I make run at 1200rpm(it's top speed). Don't forget, I still have two other fan next to it, P180 design..
System temperature past from 37 celcius at 29 celcius at idle!!!! This is very good, and don't forget that the system is still overclocked. But idle temps are not important when you overclock, so let's run two instance of Prime95, one per core.
Temperature rised again very fast, but did not go over 50 celcius, which is acceptable. Remember, I was getting this temp at idle whith the stock cooler with the fan fully on at 5600rpm and a massive headeck.
: If you are a SLI-DR Expert/Venus user, depending on your case, the Ultra-120 might not fit. Since the CPU socket is to the right of the motherboard and the socket is left to right, compare to upside down on others LANPARTY's, the Ultra-120 might touch your optical drives.
