Cooler Master ATCS 840 Aluminium ATX Case

Test Setup & Results

Test Setup & Results
While hardware such as graphics cards and power supplies are always extremely easy to test and the results they produce easily comparable, cases are a different animal all together. You can't (unfortunately) just install a copy of CaseMark06 on the machine and read back some numbers once it's done. Therefore, Overclock3D has a standard testing methodology and set of hardware that is used in times like this, so that we can at least get a rough feel for how the case performs.
CPU: Intel Core 2 Duo E8400 @ 4.0ghz (1.40v)
Graphics Card: ASUS HD 4870X2
Motherboard: Asus P5K3 Deluxe
Hard Drive: 1x Hitachi Deskstar 80GB 7K80 SATA2 7200RPM
CPU Heatsink: OCZ Vendetta II

Today we will be placing the Cooler Master ATCS 840 head-to-head with another similar sized case currently in our labs; the Lian Li v1010. To ensure that we didn't give either of the cases any unfair advantages only the stock fans were used during the testing. In addition to this, all fans were connected directly to a +12v molex to prevent any potential skew in the results from the motherboard trying to manage the fan speed.

Temperature readings for the CPU were taken using OCCT, GPU via ATITool and System / Hard Disk via digital thermal probe. While we fully understand that the results taken using software appications may not be entirely accurate, they serve only to display the comparitive differences between the two cases when tested under the same conditions.

At idle, the ATCS 840 is already showing its superior cooling performance by keeping each of the components at least 3°C cooler. It is worth mentioning at this point that despite each of the fans inside the 840 running at full speed (12v), the overall noise emmited from the case was lower than that of the V1010 and barely audible above the 4870x2 GPU cooler.

At load, little changes in terms of CPU and GPU temperatures, with the ATCS 840 still keeping things around 3°C cooler. However, while the system temperature inside the V1010 hits 41°C, the ATCS 840 manages to keep everything an impressive 6°C cooler at 35°C.

Wow what a gorgeous looking beast and I agree with the areas that you highlighted for further improvement. I've gotta get me a black one of these Quote

wow that's stunning! i'd easily have one of these with a full black interior possible window or mesh side panel and a BLACK badge... hrm...

I'm due a new case, be nice to have one thats basically ready to go for watercooling too... tempting...

how much is this? i didn't see a priceQuote

Been waiting for this review.

Absolutely gorgeous case though, easily able to hold it's own against a Lian Li or Silverstone. I also like how they took all the good bits from the Cosmos S aswell, the tool-less drive bays and radiator-compatible roof particularly.

Also, lovely artwork on the front of the box, if a little out of place.Quote

That case is stunning . Love all the little details. This would definitely be in my case wishlist xDQuote

Wow Jim thats a great review as usual! I think thats a lovely case with some insane cooling, but I dont get how they can call it an ATCS At least to me the ATCS cases were nearly all smallish mid towers with beautifully simple design...

Even though I've butchered it a lot, my old Praetorian (last rev. ATC-201 in black ano) still makes me go wow at the engineering involved, if you took out the fans, switches, LED's and the front IO thing you wouldnt be able to find a piece of plastic in the whole case.

The ATCS 840 is lovely but I don't have one on my christmas list. If anyone from CM can read this (yeah right ) come out with a beautiful mid tower (think ATC-110), and I'll buy one, maybe even two!

On a side note, didn't CM fire the ATCS engineers years ago and they went to work for silverstone?
