Ace-the lower pwm temps are obviously explained. If you hit up my oiriginal thread, there is much more information--I only summarize the results here. All testing was done with the IFX-14 mounted so that exhaust would be over the i/o port, airflow parallel to the video card. That's the only way to support 38mm thick fans on the intake side of the heatsink. If you put fans in the intake position, or in the middle position, the fans hang below the heatsink and generate a flow of air under the heatsink, that runs over the pwm coolers. On the Ultra120X, this flow exists, but is minimize because the fans naturally sit much higher (because of the clips and the mounting mechanism), causing there to be airflow above the heatsink instead of below.

I don't own any standard cases, so I can't really test that. These parts are destined for this case here, so we'll see how temps turn out. Testing this heatsink was a bit of time coming, but a) I work a full time job b) my modding earns me money whereas this sort of thing is done purely as a service.


Lad-I'll try it, but I doubt it. The air temp in one pass thru a heatsink is only minimally changed. If I reach over and feel my exhaust, it is only a tiny bit higher than ambient. A lot of people feel their case exhaust and it is very warm, but remember, I'm working with an open bench. Most case exhausts are warm because they are recirculating air in the case because of inadequate exhust. See Ace's post above. On the other hand, air pressure is a huge factor, and aiming 2 fans at each other cause a big effect in reduced airflow. I suppose I could bend the heatsink towers at an angle, but then the fans would no longer fit.



Thermalright's a great company, I think my first Thermalright was an sp-94. Like the Ultra 120X and the IFX-14, I picked up an XP-120 the day it was released.


Comparing aircooling to watercooling is useless. If you look at my case mod link above, its obviously set up for watercooling, but I got stalled out trying to put together watercooling parts--have to modify my pump, one block got lost in the mail, used radiator's rusted. I still have plans on making this case watercooled--thinking about running clear pvc hard lines!
