Thermochill PA140.X (For use with 140mm Fans) Voice Your Opinion!

[MaxxxRacer]

Now that Marci has spilled the beans on the Thermochill PA140.X Prototype I felt the need to see what you guys think of the idea. Who knows, if enough of us like the idea we might get a production PA140.X radiator.

From what I could gather the radiator will be designed like a PA120.X but will be a bit wider and longer to accomdate 140mm fans like the 140mm Yate Loon fans Crediki uses. If this radiator were put into production those of you who strive for silence but have hot systems would benefit from the added surface area and larger, higher CFM fans.

EDIT: My personal Opinion is that its a great idea and if I could find a case that I like (aka is designed for silence) I would buy the largest 140.x series rad I could fit into it.

Here is A Quote From Cathar on the PA140 Series

Okay, to repeat selected information that I posted in this thread, which details physical size and performance.

PA140 History

Marci and I both realised that the PA160, in the flesh, was a fairly large radiator. This was in part due to Thermochill's use of their hi-flow end-tanks, and so didn't quite fit into as many cases as was hoped for, and so the PA140 concept was born. Time-wise, we're talking around 22 months ago now.

Since the PA140 was specced much later than the PA160, and also had the benefit of having data from the first round of PA120.x design & test sequences to draw from. It was also designed to perform better at the lower ends of the fan speed ranges (<60cfm), rather than the 50-80cfm of the PA160's original design. This was settled in after much research with actual fans searching for acceptably quiet physically existing fans, and not just trusting manufacturer specs. In a nutshell, if a fan is specced for >60cfm, it's gonna be noisy when run at full speed, and also fairly noisy even at lower speeds due to the beefier motor bearings. No ifs, buts, or anything else. Reality is what it is.

Performance of the first PA140 prototype

The PA140 performs very well. It is only a first-stab prototype, and further performance was eked out of the PA120 design after the first PA140 prototype was specced, so the PA140 prototype may not be as highly performing as it could possibly be, but it'd be pretty close. Might be another 5&#37; to gain, with an upper stretch possibility of a further 10%, but not likely. In my testing it actually outperformed the PA160 by around 5% with low speed fans (~25cfm), level pegs with the PA160 at ~50cfm, and loses to the PA160 by around 10% with 100cfm fans. Given that it cedes a 30% facial surface area loss to the PA160, that is a fairly monumental achievement, and highlights the advances we made together with the PA120 design.

If you love using very low speed fans, and can still fit a single slightly over-sized 120mm fan based radiator in-case, the PA140 prototype is the best single slower-speed fan radiator I've tested. For stronger & noisier fans, stick with the PA160. Coupled with a slow & quiet 140mm fan, which was Marci's and my final design intention, the PA140 would make for an extremely compelling compact format single-fan low-noise radiator solution that would fit into far more cases than the PA160.

Physical Size

The PA140 prototype's external dimensions are 145mm wide x 185mm long x 50mm deep (without shroud).

A 5.25" Drive Bay slot is 147mm wide.

A PA140, would therefore fit, just, within a 5.25" drive bay.
