Heatsink Construction & Design
Heatsink Construction & Design
As mentioned before, this cooler is for all intents and purposes a tower cooler which has just been scaled down to chipset size. Yes, this lil’ guy is only 94mm high, but other than its smaller size, is really is a small tower cooler. To me this is a good thing since it means Coolink isn't trying to be fancy or a trail blazer, rather they have gone for the boring yet dependable route. When you need to cool an overheating chipset (say from trying to push the FSB to 500+) you don't want fancy, you don't want interesting, you simply something that just works. The tower design has been proven time and time again to be one of the most efficient thermal designs we have. Maybe in the future some trail blazer company will come up with something better, until then the time to be a guinea pig is not when your chipset is reaching 90 degrees Celsius. Bad things can happen when you try to get fancy.
Please don't get us wrong, boring and dependable doesn't mean it has to be ugly. Rather, form simply has to follow function. In the case of the ChipChilla its plain looks are actually a good thing as they contrast nicely with the fan and that gives it a unique look (one can could even say that it has a style all its own). When you take a good look at the design of the ChipChilla you realize that it is not just a pretty face, but is rather solidly constructed. The heatpipe itself is copper that has been plated to give a shiny bright metallic silver color which blends well with the 36 aluminum heat fins. Even better still is the fact that both ends of the heatsink have been capped, giving it a nice clean look when viewed from above; and lets face it, for the majority of its life this is the face that people will see when they look in you case window at LAN party.

As mentioned, there are 36 of the small aluminum fins that when added up give the ChipChilla a surprisingly large surface area. One interesting thing about these fins is that ChipChilla did not take a page from the Silentator and instead of giving the fins a slightly concave appearance they are completely flat. This is too bad as this flat style fin arrangement does have a tendency to increase static pressure as the air coming from the fan suddenly hits a wall of pressure that it has to overcome. Whereas if they are curved slightly different parts of the fin assembly is cooled at slightly different increments thus reducing the overall static pressure. The easy way to think about this is to imagine a phone book. If you try to just rip that sucker in half you are going to have a tough time of it, but if you bend the pages so that the individual pages can rip separately you can tear it up with very little effort. The other problem with having just a flat side is that some air will escape around the edges of the fin assembly rather than go through, this will reduce the amount of air available to the unit for cooling and does in turn reduce its effectiveness. To compound matters Coolink also went with extremely closely spaced fins which also increase static air pressure. Would it have been more effective to have less surface area (say 30 fins spaced further a part) then have more area both densely packed fins? It is an interesting question and one that only Coolink can answer, however, if the fan is up to the static pressure task all that extra surface area will pay dividends.

Even though it looks as if the ChipChilla could accept a second fan (after all it does have two wire indents per side), and this would certainly have alleviated any concerns when it comes to static pressure, it can not. We will get into more detail in the fan section with regards to the mounting system but suffice to say that this heatsink has been designed with one fan and only one fan in mind. This certainly is a shame as some of the new chipsets (and some of the older ones for than matter) can easily get to above 90°C and anything which could help reduce these insane temperatures would have been welcome.

On the positive side, the base of this unit has been designed in such away that it can accommodate both the pin mounting method and the wire tension mounting method. Since the pin mounts are pivotable you can not only ensure a good solid mount but can also skew the unit so that it is not blocking, bending or even touching anything else on the motherboard. This gives the unit a good bit of installation flexibility and does make it suitable for just about any motherboard on the market.

When one takes a close look at the base of the unit, you quickly realize that the heatpipe has been wedged in between the copper base and the aluminum top. This ensures that there is a good contact between the base and heatpipe which ensures that the heat transfer is maximized. It is the small things like this which help make or break a chipset cooler. After all, you can have half a dozen heatpipes but if they are not in good contact with the copper base then they are wasted and are nothing but glorified visual aids and not thermal transfer pipes (aka heatpipes).
On the positive side, while the individual fins are made from thin aluminum (and thus feel a little fragile) the ChipChilla as a whole is a very sturdy unit. It exhibited very little flex when tapped and in fact feels very durable in one's hand. Overall this unit is a lot like its bigger sibling the Silentator in that Coolink obviously didn't take any shortcuts when it came to it's construction.
