Not too many people have heard of a company by the name of Coolink, but that may change in the very near future. This company is creating some new heatsinks that aim at the overclocking crowd, but can they succeed? Come join Mike "Darthtanion" Wright as he takes a look at one of this fledgling company's coolers; namely the U1P2 HSF. Its a strange name for a strange looking cooler, but the bottom line is results, and you may just have to take a second look when you see how it performs.
IntroductionFor most of us, the name of Coolink is probably something of an unknown. It was to me as well until I was contacted by this company and asked to check out their new line of coolers. The Coolink name is actually just a brand name that is owned by the Kolink Company. What all this means is that we have a brand new company that wants to see if they have what it takes to enter the cooling game. And not only that, but they are doing it with the aim of bringing their lineup into the world of the Enthusiast!Can this be done by a fledgling company? Well, the only way to find out is to put their cooler through the torture chamber and see if it's still breathing at the end. So let's see what we can do with this new U1P2 cooler, shall we?

I've seen some pretty wild looking coolers before, but the sink on this one ranks pretty high on the out of the ordinary list. The heatsink itself is made of aluminum and has 24 fins that go through the entire unit. Not only that, but the fins are of varied height too. We'll have to see in a bit whether this idea works when it comes to keeping the processor cool.One of the first things that you notice when taking in this sink is the brute size of it. This isn't a little toy, but a monstrous chunk of metal that is large enough to fit two full sized 60mm fans. So how big is it? How about a whopping 67mm x 120mm x 44mm (without fans). Talk about a behemoth!But with all that girth, will it mount on a motherboard without getting in the way of all those capacitors around the socket? The answer is YES. Here's why...
Notice the raised area that is on both sides of the processor? This is a full 25mm above the base of the sink. This will give you plenty of room to clear even the largest of capacitors. In my case, it even sat comfortably above the fan that covers the Northbridge of the mainboard. What this means to you is that you should have no problems with the size of the heatsink unless you have items close to the socket that stand over 25mm above the level of the processor's core.The Base
The base of the sink is a copper plate that is adhered to the aluminum sink itself. The lines you see in the picture above are the machining marks from where Coolink has planed the base flat. Though it may not look it, the base was quite smooth. For those who are into polishing the base, a quick attack with some emery cloth and a bit of polish will have you shinier than a new penny.
The picture above shows the copper base as it is attached to the aluminum heatsink. Since there are no pins visible in the base, this leads me to believe that the copper plate is simply glued onto the sink. We'll have to see how well it can hold up to the pressures of cooling with a setup like this.The Fans
WOW...what have we here? We already knew that this was a twin fan model, but those fans hide a very nice surprise underneath. They're YS Tech fans! This is a very nice thing indeed. YS Tech has a reputation of putting out some of the best fans on the market, and they tend to be just a bit quieter than the Delta models. These fans also have the standard 4-pin Molex connector for power, and a separate 3-pin connector for the monitoring of fan speeds through BIOS and software.Now that we're over the pleasant discovery of the branded fans, let's take a quick look at what we have here. The fans included with U1P2 cooler are 60mm x 60mm x 25mm, spin at approx. 7,000-RPM and have an impressive 40-CFM airflow each. Of course, the fact that we have twin monsters means that we will also have a louder overall sound level. Can the cooling potential overcome the noise level? We'll be answering that question in a little bit when we start the testing.The Clipping Mechanism
Though there is nothing outrageously fancy about the clip on this unit, it does use all six lugs on the socket. This has come to be a blessing for those who have accidentally broken the center lug of their socket. And even if you haven't had the misfortune of breaking off a lug, it still makes the heatsink sit more firmly atop the processor.Though the clip didn't require a lot of pressure to mount, it did take just a little adjustment to get it seated correctly on the core. There is a good bit of wiggle room between the clip and the sink, so when you get the back set of lugs hooked in, make sure that you move the heatsink back toward it before attaching the front of the clip. This will ensure that the heatsink is in full contact with the processor core.Other than this, the clip attached the sink with no problems. It didn't take a huge amount of pressure to get it set onto the lugs, and the slot was just right for setting a flat bladed screwdriver in and putting it over the front lugs. If only all clips were this easy to install.

TestingAs most of you know already, I recently went from the old Thunderbird to a newer Athlon XP processor. I have been running it at stock speeds during heatsink testing so that I can maintain a stable baseline for the coolers that come to TweakTown. So let's take a peek at the test system:Antec SX1030 Tower Case w/ 170-CFM airflowEPoX 8KHA+ MotherboardAMD Athlon XP 1800+ Processor512MB Crucial PC2100 DDR MemoryProlink XX-Player GeForce3Seagate Barracuda 40GB @ 7200-RPMArctic Silver IIThe Athlon XP processors have lower operating temperatures than the older Thunderbirds, so I have begun a new database of results. With all of the new coolers coming out, it won't take long to build up a large list again. Testing will consist of my usual battery of programs so that we can maintain some consistency in the results. This will include temperatures being taken at idle, after a grueling Quake III Arena Deathmatch, and after a continuous looping of the 3dMark2001 Demo.Voltages are set at 1.75v for the processor core, 2.6 for the DDR memory, and the ambient room temperature throughout testing was a stable 21.6C (about 71F). These conditions were constant with no fluctuating temperatures or voltages.Results - Idle
Hmmm...It's beginning to look as if we may have something here. While the idle temperatures don't tell the whole story, it does tend to give us an idea as to how well the cooler can work. So now let's see what it can do when we stress the processor.Results - Quake III Arena
This Coolink is looking better and better all the time. It's does tend to be on the loud side, but these results are making it a very workable solution. Now on to the Demo Loop test.Results - 3DMark2001 Demo Loop
The twin fans have paid off very nicely here. If you can take the noise levels, then I think that you'll enjoy the performance levels that this monstrosity can give you. Very nice indeed.

ConclusionLet's go over what we have here today. We have a HSF that is huge, has two quality fans, and sounds like it wants to take off when you boot up your system. We also have a cooler that performs like a champion on steroids. All this from a relative newcomer to the performance cooling game.Now while the performance is outstanding, this cooler isn't without its flaws. If you don't adjust the heatsink backwards when installing, it could result in it not being in full contact with the processor core. And like I have stated before, it is LOUD! But many of us who have used quality heatsinks before have come to expect the noise, so this isn't too much of an issue.Because of the youth of the Coolink Company, pricing isn't yet available for these heatsinks. I have, however, been in contact with some of the people who work for Coolink and I'm estimating that the entry fee will be very acceptable. I'm guessing that they will be priced in about the mid-level of heatsink prices. Not too bad for a cooler that does an excellent job.Bottom line...If you want a HSF that performs well under pressure (and who doesn't), then take a look at this one. It offers up superb cooling at what looks like will be a very reasonable price. Though a bit on the loud side, the results should make up for the added volume.- ProsExcellent coolingYS Tech fansCopper base- ConsNeed to adjust sink before attaching front sideHigh sound levelsRating - 9/10
