When considering building a new rig or even enhancing a current one, one thing to consider is a new heatsink if you're having problems pushing your CPU to the next level. Xigmatek created a behemoth of a heatsink; Thor's hammer is a large heatsink with a rather special staggered fin design, nickel plating, and Direct Heatpipe touch. Right out of the box Thor's Hammer is ready to go, without any fans. Seriously, Thor's Hammer is a passive heatsink but you can buy fans for it if you desire. Thor's Hammer can be used on all of the latest CPU sockets but we'll just say it's limited to AMD sockets 754 / 939 / 940 / AM2/+ / AM3 and Intel sockets 775 and 1366. So just how will this one stand up against the competition? Let's read on and find out.

Closer Look:

So let's get down to business. Just by the sheer size of the box alone you can tell this one is large but what else can we find out on the box? Well, just on the front we are informed that this heatsink features "Double Layer Heat-Pipe Direct Touch." Isn't that a mouthful just to say that the heatpipes are in direct contact with the CPU? On the right side of the box you can get a closer look via a picture of the fin design as well as an up close look at the bottom surface of the heatsink. Looking on the left side you will find the main features of the heatsink again but in German, Japanese, Spanish, and Russian. Finally on the right you get a chart of specifications. Overall the box has a very artistic look about it and the box itself gives off a rainbow glow when the light hits it.











Now out of the box you will find that no fan is included but this heatsink works just fine with or without a fan. The backplate can be used for both 1366 and 775 applications and it also comes with a clip for AMD applications. For our purposes we simply take the screws and secure on the clips for 775/1366. With this heatsink you will have some leftover hardware. In the case of an Intel setup you'll be left with rubber fan clips (if your going fanless otherwise no) and the AMD clip. On the flipside you'll be left with fan clips and four springs and screws as well as the backplate. So maybe not the most efficient compared to the CoolerMaster Hyper 212 Plus in terms of you having leftover hardware but I can't complain.




With that out of the way, let's get a better look at this behemoth.

Closer Look:

So curiosity got the best of you did it? Let's get a good look at this heatsink. Thor's Hammer is one big nickel plated beast so it does compare to the ThermalRight TRUE Black edition, nickel vs. nickel, in terms of plating of course. This is much larger than any heatsink of its kind that I have ever seen. Its sheer size is probably what gives the heatsink the ability to be passive. Apart from its size you will also notice the way the fins are staggered. The staggering allows more fins to fit in the area between the base and top of the heatsink, presumably to give the heat more opportunity to dissipate. The heatsink also features a second set of heatpipes on the inner portion of the heatsink so its got more than enough metal to pull heat from your CPU.













Now Thor's Hammer comes with no fans but that doesn't mean I won't provide some to test with it. Fan mounting goes as seen below in the pictures. You pull these rubber mallet like things through the hole in the fan on the side facing the heatsink. Then you push the rubber mallets into the grooves on either side of the heatsink until they are snugly fit.




In my previous reviews of heatpipe touch heatsinks I often ridicule them for not having a fully flat base. This one has some gaps in between the heatpipes and contact surface too but what I noticed on Thor's Hammer in particular is how much smaller these gaps are compared to others I've reviewed.




Apart from what you see there, there is the installation. Installation I would say is a bit more challenging than most. They want you to use 3M tape to secure the backplate to the motherboard so then you can drive the screws through the holes in the heatsink brackets. Normally I'm more apt for a design that has the backplate just stay in place using the holes in the motherboard to keep it there and this does have that but only for socket 775 sadly. Because of Thor's size it's hard to get into the screws to secure it down so a mini wrench is provided. The only problem with this is that it's so tedious and takes a long time to get the screws fully in with this little wrench. Other than securing it to the board you probably won't come across any clearence issues between base and the fins but watch out since Thor's Hammer is a bigger heatsink you could run into other things inside your case so prospect the way you plan to mount it first. In my case I can't have this heatsink set horizontal with fans however without it fits just fine and it fits fine vertically as well.



Well now that we're all setup I've got a good review ahead so read on.

When testing Thor's Hammer and the other heatsinks I used Prime95 v25.9 to achieve full load when testing load temps while both overclocked or stock. To get temperatures during testing I used RealTemp v3.00. When idle testing I left the system sit and remain idle for up to thirty minutes after which I recorded the temp at the time. When testing for load temps I would allow the system to remain at full load for up to an hour and then record temps. As a bonus I included tests done with fans. For fans I used two Scythe Kaze Jyunis (110CFM @ 37dbA).

Lower Temperatures = Better


Wow, Thor's Hammer did pretty well. It even bested the TRUE by one degree though in only one test. All other tests it kept up pretty well. I was amazed by how well it worked passively too. So I would definitely have to say that if you're looking for a decent silent setup, Thor's Hammer would be the way to go.


Throughout the review I was really rooting for this heatsink. I was originally optimistic at the idea of having a passive heatsink and consequently my optimism was definitely not misplaced. Thor's Hammer turned out to be everything I expected of it and it really took the cake in terms of performance compared to any other heatsink I have reviewed thus far. Thor's Hammer even beat out the TRUE by a whole degree in the idle overclocked test. To say I was amazed would be a harsh understatement.  If you are honestly looking for a good silent setup, Thor's Hammer by Xigmatech is the way to go. This heatsink will run you about $64.99, which isn't too pricey either. It's only cheaper than a TRUE by $5, though I'm not too sure if it beats it out price/performance wise but it comes close than any other heatsink I've seen yet and it uses a direct heatpipe touch, which I have up until now not seen a decent performing heatpipe touch heatsink. Overall, the only con I can really speak of is the tough installation I had with it, but apart from that this heatsink performs very well.
