Provided By: Coolink Europe & Thermaltake USA


Every once in a while a company comes along seemingly out of nowhere and has a line of products that are incredible.  We were reasonably impressed with the performance of the Coolink Silentator that we looked at back in July.  They have expanded their product line to include chipset coolers like the ChipChilla that we looked at last month and now the GFXChilla which we are looking at today.  This heatpipe enabled cooler will be going up against the Thermaltake DuOrb HSF on a G92 flavored 8800GT and we'll find out how good both of these coolers are on a wildly popular graphics card.

In this review, we'll cover each product separately then put them head-to-head when it comes to testing.  We've kept everything equal and fair in this review so that you can see if the new kid on the block has what it takes to knock down a HSF heavy-weight like Thermaltake.


Coolink GFXChilla - First Look:

The Coolink GFXChilla comes in fairly plain box and has a window on the front that allows you to peek at the cooler.  There really isn't anything eye-catching on the package, but we can't judge a book by its cover.  In the package we find the main cooler, and an assortment of little heatsinks designed for RAM cooling, VRM cooling and MOSfet cooling.  There is also some thermal paste, foam "shims" and enough hardware to mount the cooler on most current graphics cards.

The GFXChilla has a big footprint and a nice low profile (for a two-slot cooler).  All four of the heatpipes run to the aluminum fins and are cooled by means of two 80mm fans.  These fans are nice and thin and measure in at 1cm thick.  They have proven to be very quiet and are cannot be heard over the other system noise.  The mounting surface is located clear at the bottom of the cooler and this should allow mounting on cards where the GPU core is right close to the slot.  This design should also allow the cooler to protrude a bit from the top side of the card and bring cooler air into the fins.  It's a good idea and we'll see how it plays out on the following pages.

Before we tear off the stock cooling from our test card, we'll take another look at the heatpipes and a closer look at the bottom finish of the GFXChilla.

As you can see above, the bottom finish is not super smooth and polished.  The machining marks are clearly visible although the block feels super smooth.  We'll have to see how this plays out through testing.  Also you can see that the heatpipes exit parallel to the block and are very close to the bottom.  My concern is that they won't allow proper mounting of RAM sinks - and we'll find out in a minute.

Employing 4 high-performance heatpipes and two large 80mm fans, the GFXChilla provides superior cooling performance at minimum noise levels. The GFXChilla is widely compatible, simple to install and can easily be upgraded.

  • Four 6mm heatpipes for excellent heat distribution throughout the cooling fins
  • Two large, low-profile 80x80x10mm fans (18dB)
  • Low profile: takes up only 2 expansion slots
  • Incl. self-adhesive aluminium RAM & VR heatsinks
  • Easy installation and broad compatibility



This cooler is compatible with many graphics cards of this generation and even last generation.  Coolink supports 6600, 6800, 7600, 7800, 7900, 8400, 8500, 8600, 8800GS, 8800GT, 8800GTS 512MB and even the new 9600GT.  They don't support 7900GX2, 8800GTS 320MB/640MB cards of the 8800GTX/Ultra cards.  On the AMD side of things they support everything but the Radeon 2900 and 3870X2 cards.

On the next page we'll cover installation of this cooler on the 8800GT.
