Benchmarking - Thermal
Today, we begin applying our new thermal benchmarking methodology to mid-tower cases. In the past, we have measured the temperatures of only the key components of our test bed, which provided only a little insight on how well the cooling systems in each case worked. Our new process not only shows the temperatures of the components installed, but also the temperature of the ambient air around each component.| PC Mid-Tower Test Bed | |

The thermal readings for the key components and points on the motherboard during operation were as follows. The numbers in each square represent the temperature of that particular section of the case in degrees celsius:

The warmest regions in the GB2 are around the CPU, PSU, and chipset areas. From the lower temperatures at the front of the case it is safe to assume that all of the warm air is being pulled towards the back of the case and out through the PSU as well as the rear 120mm exhaust fan.
Here are the temperatures of the various key components in the system. Temperatures have been taken directly off of the surface of the hardware this time for an accurate reading of actual component temperatures.

We measured the temperature of the CPU's heatsink at 35 while the core runs as hot as 51 degrees under a few minutes of constant 100% CPU load. The VGA card's heatsink ran extremely hot as we have observed in past instances at about 52 degrees while the GPU's core ran at 67 degrees while running a graphically intense application. The front intake fan kept our 120GB Barracuda at 36 degrees throughout our benchmarks which kept us happy.

does anyone else think its unfair and incredibly biased (and unjournalistic) that they dont make a single mention of the noise this thing puts out in the conclusion? come on! this thing is on par with the noisiest case they've ever reviewed and they do all they can to skirt the issue. this thing is as loud as a f*in lawnmower! BS, if you ask me.Jackular - Tuesday, December 14, 2004 - link
Good to see that the case fans are with the 3-pin connectors (I got Zalman's fanmate and multi-connector to get the fans into different volts). It's loud as default (with 12V) but how "loud" are they at 5V or 7V? This is something I would really like to know about.ViRGE - Tuesday, December 14, 2004 - link
Looking at the case, for the price given, there's 1 critical flaw that really hurts it: the placement of the front Aux ports. Aux ports are only useful if you can reach them, and the bottom of the case is next in the line of unreachable spots just head of the rear of the case. If I'm buying a high-end case, the Aux ports MUST be at least mid-way on the case if not ideally at the top.Noli - Tuesday, December 14, 2004 - link
The question on value is simple - $240 for the (near equal) noisiest case Anandtech has review is crap value plain and simple. This then begs the questions others asked about the fans. It seems very strange that 2x 120mm fans should be so loud so does replacing them with decent alternatives (panaflo etc) put it on par with an Antec with 2x 120mm in terms of noise? I'd hope with such a discrepancy that a little bit more journalistic investigation would have come naturally - if I spend $240 I want to know if replacing the fans is a solution or if there is an inherent flaw in the design. Apologies for rant.Wolfz - Tuesday, December 14, 2004 - link
What is the heat performance like with the third fan installed?Would switching the fans to (better/quieter?) ones reduce the sound significantly?
Are they suppose to be stuck at 3200 rpm's, I thought it was standard to have variable speed fans running inside the system. Is there any sort of mod you can do to handle that?

I think the different length stand-offs were for different sized boards. The 1/3" are for universal locations, and the 1/8" with the add-on part are for customizable locations for different board sizes. That seems reasonable to me, and not a negative. Also, thanks for finally agreeing that a removable MB tray is not such a great feature. I got tired of seeing cases ripped for something that even most enthusiasts don't use. Now, about testing cases with their own PS's. Do them with the stock PS, and with your own so I know if I need to buy a new PS with the case or not. Better yet, benchmark the PS if it is a part of the sale just like you would any other part of the case it comes with.Good review by the way. Keep up the good work, and remember you can't please everybody, so try to please me instead.

I was really starting to like the case until I read the price. I was expecting half of that, at the most. Jesus.TinyTeeth - Tuesday, December 14, 2004 - link
Interesting. But damn, a Coolermaster Wavemaster with 120mm fans would be perfect!LoneWolf15 - Tuesday, December 14, 2004 - link
In response to #6, I agree on the dodge about whether this case is worth our money. I also agree with #8, finally a review of a case that isn't a downright tacky pre-mod.I had wanted this case at one point and waited several months. However, I had extremely poor communications response from Chenbro, who ignored two of my three e-mails, and never gave me the information I needed on pricing and availability. I ended up buying an Antec P160 with the window, and modding a custom 120mm blowhole on top, a feature that I wanted that the Chenbro has. I'm glad I bought the Antec; $240 even for a case as nice as the Chenbro is ridiculous. I paid half that for the Antec, which is a topnotch design, and used the money I saved to do things like sleeve the power supply and rebuild the system.
One more thing: The review was very well done on the case itself. My compliments, it's one of the better reviews I've seen here in a long time.

$240?!? This isn't a server case, it's a gaming case. I'd rather blow the 240 on a video card or a 500GB RAID 0 SATA array. Maybe they should call it the Chenbro Duesenberg!
