Arctic Cooling Accelero S2 - Passive Graphics Cooler

Installation and Test Setup

Test Setup

To test the Arctic Cooling Accelero S2 we used the following setup:

Core2Duo E6700 ES
abit FP-IN9 motherboard
1gb Mushkin HP2 5300 (@ DDR800 4-4-4-10)
Seagate 7200.10 160gb HDD
Sony DVD-Rom/CD-RW
Silverstone 560w ZEUS PSU
Silverstone TJ09 case

The Test Subject

The ever faithful Sapphire X1600 Pro will be the subject of our review. I have the stock cooler on this card but with a slightly larger fan. Although this is very slightly cooler than the stock heatsink, it makes just as much noise!

This is an all aluminium affair done on a budget so it will be nice to see how the S2 gets on.

I used the temperature recording facility in RivaTuner and double-checked this in ATI's software and with a thermal probe.

Ambient temperature was around 21.7-22°C.
Idle Tests were performed after 30 minutes of the PC being turned on and recorded for 30mins at 30 second intervals.
Load Tests were performed after 30 minutes of the PC loading up using RTHDRIBL full screen and recorded for 30mins at 30 second intervals.

A note on airflow

The airflow that Arctic Cooling recommends to use is to have all case fans blowing out of the case to create negative pressure so that the S2 draws air into the case through the PCI backplate.

However after trying this my CPU temperature was unacceptable so I reverted to normal airflow.

I have:

* 1 x 120mm fan blowing air into the case through the TJ09's graphics card duct (standard Silverstone)
* 1 x 120mm fan blowing air over the HDD bays (Noctua )
* 1 x 120mm fan blowing air out of the rear (standard Silverstone)
* 1 x 120mm fan blowing air out of the top blowhole (Noctua)
* 1 x 120mm fan blowing air through the CPU Heatsink and out through the rear fan mentioned above (Scythe stock)
* 1 x 60mm FAN blowing air over the NorthBridge (SilenX)


Installation of the S2 was not as easy as I thought it was going to be, considering the card we chose doesn't have many screw points anyway.

I found that the RAM sinks provided weren't as sticky as perhaps they should be and needed a little bit of persuasion to stay on the card. I also found that the plastic retention clips used to keep the S2 in place were a little awkward to get into place and I knocked off the RAM-sinks a few times before I got it right.

Having said that it wasn't that difficult an operation and only took me 10 minutes or so to get through.

As you can see the S2 dwarfs our small X1600 Pro - it really dominates the card.

The heatpipes don't obstruct anything and the cooler is fixed firmly to the card with 4 screws. I've had other coolers on this card and none have quite felt that they fit, but the S2 does well and I was confident that the fit was right first-time.

Here you can see a side view and see that the RAM-sinks have plenty of room and don't obstruct the heatsink.

pci backplate installed

The S2 looks huge installed even compared to the massive Scythe Infinity. However as this is a slightly barebones install I had no issues with clearance and in fact it isn't actually a hassle to install in the case at all. Notice the PCI backplate allows airflow into the case as well.

Now the real test.

Awesome Review

And WOW, 37C using an entirely passive cooler? That's pretty damn nice!

How heavy is that thing btw? I looks like it would put a lot of stress on the card.Quote

I know I was quite honestly shocked. I had to check and double check the figuresQuote

Jeeze thats big. You rekon it could cope with the load of an 8800 though kemp? Maybe if you added a fan?Quote

21-05-2007, 11:36:41

Well the S1 has 4 heatpipes and an add-in fan module so i would guess you'd be ok.Quote
