As you know, with the recent introduction of the Core i7, CPU overclocking and cooling is a little tougher with the increased heat this CPU delivers. Even the more popular heatsinks such as the ThermalRight Ultra Extreme Series and Noctua NH12-P even have trouble cooling this beast. In any case, with overclocking a stock heatsink doesn't cut it. Of course, any old aftermarket heatsink won't do. Something with copper heatpipes is a must and even more important than that is a decent fan to deliver cool air to the fins of the heatsink.

Enter Kingwin with its 1366 solution, the XT-1264. Like the TRUE and Noctua NH12-P, this heatsink utilizes a 120mm fan to deliver air through the cooler. Not only does this heatsink offer socket 1366 capabilities but it also fits socket 775 as well as AMD sockets AM2, 754, 939, 940. A great feature to be found with this heatsink is four dual copper heatpipes that visibly make direct contact with the processor. We shall see how this stacks up to the current competition on the market later in this review.

Closer Look:

The outside of the packaging lists the potiential applications as well as stating that this heatsink is 1366/Core i7 ready. The back of the packaging is host to a table filled to the brim with product specifications as well. Nothing much else is to be found here, though it seems the box is limited to applications and specifications.








The inside of the packaging tells a whole other story with two separate bagged sets of adapters, one for 775 and the other for 1366 and of course, the heatsink. Apart from the heatsink and adapters there is a manual packed into one of the bags as well as a packet of thermal compound. While the box itself and its contents seem rather simple, it still manages to deliver what is necessary.



Now that the Kingwin XT-1264 is unpacked, let's take a closer look before we put it to the test.


Closer Look:

This heatsink is a little different than most ones that use 120mm fans in the fact that you can see the copper heatpipes on the bottom. It would appear that Kingwin is trying to get it so that the heatpipes come into direct contact with the CPU, which could actually improve heat dissipation since there is no other source of metal between the CPU and heatsink that would require more time for heat transfer. Apart from the heatpipes being copper, the rest of the heatsink is purely aluminum. Additionally, this heatsink only comes packaged with one fan and it would appear that it is not capable of using additional clips to secure another one to it, so one would have to resort to zipties for a push/pull configuration.












If you look closely at the base of the heatsink you will notice something not so good. The surface of the base of the heatsink contains ridges between the heatpipes and the aluminum portions of the contact surface. This can create areas where pockets of heat stay and where heat does not dissipate at a constant rate, which means increased temps. Nothing that a good lapping couldn't fix; however, for the purposes of this review, I take it as is. I wonder how well it will it will perform with this problem.


From my experience with heatsinks of this type, installation can sometimes prove challenging, though this one seems smaller in comparison to most of them. In fact, I can't even fit my TRUE in vertically due to a 120mm blowhole fan being in its path, but this heatsink just manages to fit in. On the flip side, I can't fit the XT-1264 in horizontally because the cooler is too short to fit over top of the PWM heatsink on the left side of my motherboard.


Now that it's all together, let's move on to testing.

When testing the XT-1264 I will comparing temps when idle and under load. I will be testing at stock speeds and at overclocked speeds to better show how this heatsink stands up to the ThermalRight Ultra Extreme 120. I tested the XT-1264 against the TRUE with one fan and with two fans in a push/pull configuration. Both heatsinks are left stock (i.e. neither are lapped). For stress testing I will be using Prime95 v25.9. I will set Prime95 to use Blend as this stresses everything so that the computer will be at the most possible load. Hyperthreading is enabled and all eight threads will be in use. I will leave this running for an hour and then record the temperature using RealTemp 3.00. With idle testing I will be leaving it idle for thirty minutes and check the temperature with RealTemp 3.00.


Testing Setup:

Comparison Heatsink:





Lower Temperatures = Better



Besides the idle stock test, which resulted in a tie between the one fan TRUE and XT-1264, the TRUE beat the XT-1264 on every test. However, the XT-1264 kept up quite well and surprised me quite a bit. I had figured that due to the gaps between the heatpipes and aluminum surface there would be a very great difference but the only test that showed the greatest difference was the full load overlocked test. Though, at a whopping 82 degrees Celcius, I wouldn't be running 3.44GHz for 24/7 on the XT-1264.


Looking at the XT-1264 I would have to say I am impressed with what Kingwin has offered up. It holds pretty close to the TRUE and even tied it in the idle stock test. Ultimately, it lost its ground in the remaining tests, with the greatest difference between it and the one fanned TRUE being 8C. i7 is a tough cookie when it comes to cooling and even the TRUE doesn't hold that well to it like it did with the Core2s, but even so, for the price, this heatsink delivers. I had figured that the computer might fail when the XT-1264 took it up into 80C territory but I was surprised when I found that it managed to keep from that for at least an hour. Moreover, I am curious that were the surface of this was completely smooth like that of the TRUE, would it be better able to stand up to it? For the purposes of this review however, I cannot modify the heatsink so I don't know the possible outcome of this. I was also amazed to see that the fan equipped on the XT-1264 was very close in specification to that of the Scythe Kaze Jyuni used on the TRUE. The only other thing that disappoints me a little bit is the fact that there is no ability to clip another fan onto the XT-1264, so you will have to use zip-ties if you want another fan on it. All things said though, with a price point of around $35 depending on where you order it , this isn't too far from the TRUE in price or performance, so the XT-1264 makes a good budget cooler.
