Thermalright HR-03 or Arctic Cooling Accelero S1 - which is better ?

I have an X1800GTO2 soft modded to X1800XT and I'm looking for a replacement of my videocard stock cooling, my two choices being HR-03 and S1.

I had an Arctic Colling Accelero X2 and a Pentagram XC-80Cu, which were OK for "normal" utilization, but when overclocking and increasing the GPU voltage they were outscored by the stock cooling running full speed.

I looked on the web for a comparative testing of the two cooling solutions mentioned above, but I've found none.

If someone tested both of them on a X1900 or X1800 series card, any advice is welcomed.

hr-03

I could test the S1, I received one this morning, but really I only bought it for the larger VRM heatsink it comes with. (I can use the S1 on something else later)

I'm fairly positive that the HR-03 is much better though, even if you strap a fan on the S1, mostly due to thicker heatpipes to help dissipate high heat quicker.

One friend of mine, tested S1 on a X1900XT using different 120mm coolers, and the temperatures were as it follows:

X1900 XT @ 655/1550 MHz @ 1.35V vGPU

Accelero S1 + Scythe DFS122512L @ 12V (~1300 RPM) - IDLE: 39*C - LOAD: 51*C
Accelero S1 + Scythe DFS122512L @ 7V (~700 RPM) - IDLE: 40*C - LOAD: 58*C.
Accelero S1 + Scythe DFS122512L @ 5V (~550 RPM) - IDLE: 42*C - LOAD: 56*C
Accelero S1 + Scythe DFS122512L @ 7V (~750 RPM) - IDLE: 37*C - LOAD: 50*C (lower ambient temperature, probably ~ 25C, while >30C for the rest of the tests).

Accelero S1 + Sunon KD1212PMB1-6A @ 12V (3100 RPM) & Sunon KD1212PMS1-6A @ 12V (3000 RPM) - IDLE: 38*C - LOAD: 45*C
Accelero S1 + Sunon KD1212PMB1-6A @ 12V (3100 RPM) - IDLE: 38*C - LOAD: 46*C
Accelero S1 + Sunon KD1212PMS1-6A @ 12V (3000 RPM) - IDLE: 38*C - LOAD: 47*C
Accelero S1 + Sunon KD1212PMS1-6A @ 7V - IDLE: 39*C - LOAD: 48*C
Accelero S1 + Sunon KD1212PMS1-6A @ 5V - IDLE: 39*C - LOAD: 52*C

(lower ambient temperature)
Accelero S1 + Nexus DF1209SL-3 @ 12V (~1500 RPM) - IDLE: 37*C - LOAD: 52*C
Accelero S1 + Nexus DF1209SL-3 @ 7V (~875 RPM) - IDLE: 39*C - LOAD: 58*C.
Accelero S1 + Nexus DF1209SL-3 @ 5V (~625 RPM) - IDLE: 42*C - LOAD: 69-70*C.

X1900 XT @ 702/1550 MHz @ 1.45V
Accelero S1 + Scythe DFS122512L @ 12V (~1300 RPM) - IDLE: 41*C - LOAD: 55*C.

X1900XT @ 730/1550 MHz @ 1.5V vGPU
Accelero S1 + Scythe DFS122512L @ 12V (~1300 RPM) - IDLE: 41*C - LOAD: 57*C

I don't know his ambient temperature, but he uses an open case test-bed. Anyway, I'm more than sure that his room temperature never went below 25C ... it has been pretty hot in Romania in the last few days: 40 - 41C.

It wasn't over 30*C in the other tests, but it was close. Something like 29-30*C. ;)

Those are some nice results, better than what I was getting with my HR-03 with a Yate Loon on it (close case, variable ambient)

Your choice! :)
If you go for TT BT you have to buy non VX version.
These are much better, but if you ask me to choose one of these (Thermalright HR-03 or Arctic Cooling Accelero S1), i will probably go for S1.

The funny thing is that I already have a TT BT. But I'm gonna let it on my CPU for now.

A need a decent aircooling solution until I'll have my waterblocks repaired. S1 is more and more tempting ...

Then go for S1 + 14mm fan (or 12mm)

... and cheaper. ;)

S1 - 20usd
HR-03 - 40-50 usd

Here, the prices are: ~ 40$ for S1 and 50$ for HR-03, but if I knew that HR-03 is 5C better, I would pick it with my eyes closed.

40$ for S1???
it is too much....does 5C any matter if you are going to use water soon?

You mean $30 US for S1 http://www.newegg.com/Product/Produc...82E16835186016

srry, i thought it was cheaper...

I tested the S1 compared to 7 others in this video card cooler roundup, unfortunately no HR-03 , sorry :(
