Coolink GFXChilla Page: 1
In recent times we have a variety of  cooling solutions employed by graphics card manufacturers in order to tame temperatures emitted by modern GPU's. In the thirst for better performance, enthusiasts often replace the reference cooler for an aftermarket solution in order to combat escalating temperatures. Furthermore, with the advent of multi-GPU setups like ATI's Tri XFire and NVIDIA's Quad-SLI effective air circulation becomes an absolute necessity to prevent overheating.
Coolink GFXChilla
Today we have been fortunate enough to have been given the opportunity to test an aftermarket cooling solution for graphics cards - the GFXChilla manufactured by Coolink. So who are Coolink and what are they about? Let's hear it straight from the horses mouth:
Coolink is a brand of the Kolink International Corporation and stands for an effective conjunction of no-frills performance, excellent quality and attractive pricing. Coolink - the direct link to affordable high-end cooling!
Established in 1996, Coolink initially was widely known within Asia and it was not until 2005 that they emabrked upon a mission to take on the European market with earnest. Now in present day form, Coolink-Europe has now became a well recognised brand for high-quality cooling components in Europe too.
Anyway, enough of the chit-chat let's get down to business by having a look at the technical specifications of our review specimen. The technical specifications were taken directly from Coolink's Product Page.

The Coolink GFXChilla has very good card compatibility with issues arising from only a few AGP cards and the obvious dual-GPU varieties. I have taken the liberty of including the compatibility list for you here.
Let's head over the page to have a look at the packaging and its contents...

Packaging and Contents
The Coolink GFXChilla comes in a no-frills cardboard box with a blister style window that allows you to see a hint of what's in store - which is nice as it adds to the excitement. The front and rear of the packaging merely serve to highlight what's included, and the sides house information on the technical specifications of the product.

After removing the blister pack from its cardboard housing you are greeted with a secure and well packaged product. Everything has been included to get you up-and-running as quickly as possible.

Included in the Coolink GFXChilla packaging are:
* 1 x Coolink GFXChilla Heatsink and installation hardware;
* Thermal paste;
* RAM- & VR-heatsinks;
* 1 x case badge;
* 1 x 3 to 4-pin adaptor, and
* Installation manual
The installation manual is very well set out and easy to follow with pertinent illustrations to guide you through the installation process.

The bundle that Coolink has included with the GFXChilla is really very good and feels 'quality'. Furthermore, it is securely packaged and should arrive safely if delivered through the post.
Now let's have a little closer look at the Coolink GFXChilla itself...
A Closer Look
The Coolink GFXChilla is certainly a sleek looking and low profile unit and the 2 x included 80mm fans compliment it nicely.

You can see from the images above and below that the fans are very thin and should provide 'near silent' operation. How well they'll cool though is yet to be seen.
I found it quite amusing that the GFXChilla looks as if it were constructed from a Meccano kit. All things considered though, the Coolink GFXChilla is very well constructed and feels very solid.
Coolink appear to have everything covered down to the last detail with the inclusion of a well braided fan cable - complete with both ends neatly heat-shrink wrapped.

The Coolink GFXChilla features a flat lapped base that still exhibits some of the machine marks left from the lapping process. The base is in no-way lapped to a mirror finish, but is quite smooth.

With the Coolink GFXChilla installed on an Palit 8600GT PCI-E graphics card it really looks the part. You can see from the image immediately below (right) how the low-profile heatsinks for the memory modules are placed in relation to the GFXChilla' heatpipes.

One issue that we encountered when installed the GFXChilla was that the fins came awfully close to touching the top of a couple of electrolytic/solid capacitors present on the PCB.

Now that we've had a chance to get personal with the Coolink GFXChilla, let's head over the page to see just how we're going to test it...

Testing Methodology
In order to test the cooling performance of the Coolink GFXCHilla I have decided to compare it against a couple of other heatsinks. I have chosen to compare it to the 'Zalman-esque' Palit heatsink for their NVIDIA 8600GT cards, as well as an Thermalright V2 heatsink. I have taken the liberty of including some gratuitous pics for those interested.

In preparing the test setup for this review I have tried to keep the fan used on the Thermalright V2 heatsink as close to those on the Coolink GFXChilla as possible. I chose to use a Scythe Minebea (3110KL-04W-B19-EB1) 80mm cooling fan. The test setup used has been included below:
Intel Q6600 G0 Processor with Intel reference heatsink
ASUS P5B Deluxe WiFi-App Motherboard
Palit 8600GT Graphics card
Seagate SATA II 80GB HDD
Thermaltake XASER VI Chassis
Palit 8600GT Heatsink
Thermalright V2 Heatsink
Coolink GFXChilla Heatsink
During the testing process all heatsinks received a fresh application of Noctua NH-1 thermal compound and to ensure uniformity of the test results, 3 installs were conducted for each heatsink. After each install the Palit 8600GT graphics card was allowed to idle for 30 minutes to acclimatise, upon which, the temperature was noted using RivaTuner 2.08
Graphic load was obtained by using RTHDRIBL for a period of 30 minutes at a resolution of 1024 x 768. Again RivaTuner was used to record the resultant temperature and an average obtained.
Ambient temperatures at the time of testing were between 27.5 and 27.9 degree Celcius and case temperatures were between 30.5 and 31.1 degree Celcius respectively.

Result Observations
The Coolink GFXChilla consistently outperformed both the Palit reference cooler and the Thermalright V2 heatsink. Furthermore, it produced these results by remaining exceptionally quiet. So quiet in-fact, I had trouble distinguishing it from the Intel reference heatsink on my CPU. Well done Coolink....

So how well did the Coolink GFXChilla perform in today's review?
There is no doubt that the Coolink GFXChilla is a great little performer, whilst not infringing on those who prefer silence, or very close to it. Build quality is also evident even though the included fans look a little 'gimmicky' and light-weight. Furthermore, the braided cable finish is also a welcome inclusion and adds further evidence that this humble little heatsink is a very viable contender for your dollar.
I wasn't able to find the Coolink GFXChilla in any of our preferred suppliers stores, and the only assistance I had in finding one in the UK was courtesy of Coolink' website. QuietPC have them available for £26.00 inc VAT which still ends up considerably cheaper than many of the alternatives out there.
Let's have a look at the break-down:
The Good
- Price
- Performance
- Low profile
- Quiet
The Mediocre
- Tight fit on some cards listed in the compatibility chart
The Bad
- Nothing to report
