A combination of unfortunate events recently resulted in an old familiar friend making an appearance on my doorstep... my old TEC rig had returned home...!
http://www.over-clock.com/marci/2003ptII/images/DSC00106.jpg
The guy I sold this to (R.I.P. d00d) sadly couldn't get his head round the TEC side of things so ran it as a standard watercooling setup. Once it got back to me however, twas time to get the TECs back on the job.
http://marci.over-clock.com/tec/S4100255.jpg
226w TEC on CPU (A64 Clawhammer 3200+), 172w TEC on GPU (X800ProVIVO >> X800XT-PE). Figured whilst I was in there I'd strip out the previous 240v Eheim1250 pump... hell... all the watercooling got ripped out basically... and refit with more up-to-date equivalents....
http://marci.over-clock.com/tec/S4100260.jpg
The radiator in this rig is the first ever ThermoChill HE120.3 prototype from way-back-when. Still going strong...
http://marci.over-clock.com/tec/S4100261.jpg
So... what was I gonna do with the rig now? Well, with the new PA Series rads finally getting sorted, figured may as well do a comparison of HE120.3 vs PA120.3 with the same fans... to do so required some monitoring tools in the form of the mCubed T-Balancer and some handiwork with silicon... thus giving me liquid in and out temps...
http://marci.over-clock.com/tec/teclatest/liqtemps.jpg
And air in and out temps
http://marci.over-clock.com/tec/teclatest/airin.jpg
http://marci.over-clock.com/tec/teclatest/airout.jpg
Add in the handy feature of the tbalancer software being able to talk to LCDC and we get...
http://marci.over-clock.com/tec/teclatest/tbanlcd.jpg
MBM5 will collect CPU temps, and ATITool will handle GPU temps. So, that was the rig all ready... time to case it all up but leave rad external (just easier for swapping it over later)
http://marci.over-clock.com/tec/teclatest/casedup.jpg
Started off with unit under full load with as much heat as possible, whilst keeping speeds at stock.
CPU was set to 1.75v. AGP VDDQ to 1.6v. 100% load inflicted.
Temps were meaured every 20mins. Surveying them, they levelled out rapidly, within an hour, and hovered around the same points for the rest of the day (controlled ambient as best possible).
Max variance in ambient temp was 1.5 deg C. This was reflected across the board.
Note, temps shown are just a quick cross-section of readings recorded, not complete end-to-end results...
HE120.3 with 3x Panaflo M1A@7v
Air<: 23.0 | 24.0 | 23.5 | 23.0 | 23.5 | 24.5 | 24.0
Air>: 26.0 | 27.0 | 26.5 | 26.0 | 26.5 | 27.5 | 27.0
Liq<: 33.5 | 34.0 | 34.0 | 34.0 | 34.0 | 34.5 | 34.5

CPU: 17.0 | 17.0 | 18.0 | 18.0 | 18.0 | 19.0 | 18.0
GPU: 19.0 | 19.0 | 20.0 | 19.0 | 20.0 | 20.0 | 20.0
< = In
> = Out
So, averages are being used.
I'll summise testing of the HE120.3 with Panaflo M1A (fans at 7.04v by multimeter) as follows:
Avg Air <: 23.6
Avg Air >: 26.6
Avg Air Dt: 03.0
Avg Liq <: 33.9
Avg Liq >: 33.5
Avg Liq Dt: 0.40
Next step - remove HE120.3, install PA120.3 with same fans set to same voltage by Rheostat (measured with multimeter). This gave me the following recordset...
PA120.3 with 3x Panaflo M1A@7v
Air<: 22.5 | 24.0 | 22.5 | 23.0 | 23.0 | 23.5 | 22.5 | 23.0 | 22.5 | 22.5

GPU: 15.0 | 15.0 | 15.0 | 16.0 | 16.0 | 16.0 | 15.0 | 15.0 | 15.0 | 15.0
Avg Air <: 22.9
Avg Air >: 28.0
Avg Air Dt: 05.1
Avg Liq <: 30.8
Avg Liq >: 30.1
Avg Liq Dt: 00.7
Already, we see a substantial drop in CPU and GPU temps between the two rads, with the PA120.3 shaving 4 or 5 degrees off each over the old HE series.
Figured I'd go for some self-amusement next...
PA160 with 1x Panaflo M1A@7v
Well... I'm impressed...

CPU: 21.0 | 22.0 | 21.0 | 21.0 | 21.0 | 21.0 | 21.0 | 21.0
GPU: 21.0 | 22.0 | 22.0 | 22.0 | 22.0 | 22.0 | 22.0 | 22.0
Avg Air <: 23.5
Avg Air >: 31.5
Avg Air Dt: 08.0
Avg Liq <: 37.4
Avg Liq >: 36.0
Avg Liq Dt: 01.4
Only 1 or 2 degrees hotter than the HE120.3 manages on CPU & GPU temps, with 2 less fans = less noise. Always a bonus!
PA160 with 2x Panaflo M1A@7v (PushPull with dual shrouds)
Air<: 23.0 | 23.0 | 24.0 | 23.0 | 23.0 | 23.5 | 24.0 | 23.5 | 24.0 | 23.5

CPU: 19.0 | 20.0 | 21.0 | 20.0 | 21.0 | 21.0 | 21.0 | 21.5 | 21.5 | 21.5
GPU: 19.0 | 21.0 | 21.0 | 21.0 | 21.0 | 21.0 | 21.0 | 22.0 | 22.0 | 22.0
Compare these figures to figures above - result? 2x fans in Push-Pull is of no major benefit over 1x fan in push.
