CoolerMaster Hyper 6 (KHC-V81-U1) Heatsink Review

Reviewed on: June 11, 2004
Everything we've ever seen from CoolerMaster has been low-priced, and low performance. Which to a certain niche, is not a bad thing. From the looks of the new Hyper6 heat pipe CPU cooler from CoolerMaster, people may start thinking about the name CoolerMaster in a whole new way.
If I were to say nothing more about this heat sink, I'd say this beast looks sweet. It actually looks like something I'd expect to see from Thermalright or Zalman, defiantly not something I'd expect from CoolerMaster. It looks nice, and well, that's probably the only kind thing I can say about it.
I'll get into the issues I've had with this heat sink in just a moment. First, we'll take a look at the specifications, features, and everything that's included.
- Six embedded heat pipes that provide superb heat conduction
- Special heat sink design - cooling performance is maintained at any angle of declination
- Raised base design to avoid interfering with components sourounding CPU such as capacitors
- The user of 100% copper fins and special welding techniques enable perfict connections between fins and pipes
- High-density fins provide a large surface area for heat dissipation
- User can choose to use an 8cm fan with higher speeds that provides greater cooling performance
- Suitable for all K8 and P4 CPUs
AMD K8 (socket 754/940) and Intel P4 (socket 478)
96mm x 82mm x 120mm
6 heat pipes + 100% copper stacked fin with copper base

As I mentioned, this thing is a beast. Looks like CoolerMaster pretty much ignored all of AMD's Thermal Solution Design Requirements (seen here on page 11. - Thanks Para! ;)) when designing this heat sink. For the most part this isn't a big deal. Thermalright, Zalman, Swiftech, and other companies have been ignoring requirements for years, and they've worked well.
Installation, Testing, & Problems
Just a note.. This is a P4 and K8 heat sink. For this review, we will be installing, testing (well, we were going to), and reporting problems with this heat sink using an AMD 64 (K8) system.
At the beginning of may, I reviewed a Foxconn motherboard. The day I finished the testing for that review, I started working on reviewing this heat sink. That's how long I've been having problems with this beast.
The first problem I ran into was that the Hyper6 doesn't use the standard type mounting equipment (retention frame) found on the Athlon 64 motherboards. While it's not a huge deal here, the problem was (which is also noted in the review) the Foxconn motherboard's retention frame could not be removed. Below you can see the standard frame (left), and the one that came with the Hyper6 (right).
Thankfully I had the Chaintech ZNF3-150 motherboard that I could use. Again, we still have to remove the standard retention frame, and use the one that came with the Hyper6.
With the new frame now attached to the motherboard, you can apply your thermal compound to the CPU and to the base of the heat sink.
Before you go to put the heat sink on the CPU and try to fasten it, you'll have to remove the fan (if you attached it). This heat sink cannot be mounted while the fan is on the heat sink. - CoolerMaster's instructions make note of this as well.
So, it's time to actually fasten the heat sink to the retention frame. The first problem is you now have a 2lbs metal block (for the most part) sitting on top of you're CPU. Not the end of the world, till you go to fasten down the two clips.
Trying to fasten the clips was like trying to push a pop-rivet into place using only your thumb. In fact, so much force was exerted trying to attach the Hyper6 to the retention frame, I didn't think there was any way the CPU could have survived. Thankfully, after all was said and done, the system booted.
Just think... this heat sink was so much fun to install the first time, if you ever plan on moving your computer (e.g. to another room, or LAN Party), you'll have to remove the heat sink, move the system, and reinstall the heat sink. - Same thing you are suppose to do with many other heat sinks, just more painful with the Hyper6.
Since the heat sink was installed outside of the case, it wasn't till the motherboard was put back into the case, and the components were put back into place that I noticed the next thing.
No matter which spot you put the fan on, you're not going to get a whole lot of air flow into the heat sink. If you had a full tower case, this wouldn't have been as much as a problem, since you'd have more room between the PSU and the heat sink. However, this test rig is a mid-tower (Kingwin blah blah blah), and space is precious.
Figuring that I had messed up the thermal compound when attempting to attach the heat sink, I decided to reinstall the heat sink... 4 separate times. Each time, I encountered the same issues. After that, I'd had enough of this thing.
Due to the awkward and difficult mounting method of the Hyper6, it is virtually impossible to mount the Hyper6 without rubbing the thermal compound around, which of course is going to hinder the cooling process. While I can’t say for certain whether overheating of the RAM or the CPU was the culprit giving the BSODs (I’ve seen it many times over the years, and I’m sure many of you have as well), it could be one or both of them. I do know without a shadow of a doubt, that the problems were directly related to the Hyper6/cooling. Install any other heat sink, and the system is fine, install the Hyper6 and “Houston we have a problem”.
Well, this has definitely been an (unpleasant) experience for me. I tried my darnedest to get this heat sink to work, and I badly wanted to like it. No matter what I tried, this heat sink was just plagued with issues. One thing to keep in mind the individual components used in my testing rig. Each system is different (for the most part), and the Hyper6 may work well for you. In fact, I've seen many positive reviews of the Hyper6 on P4 based systems. Just do some research.
Right now, I am skeptical, but with any luck, the problems I’ve had may just be related to a few motherboards. Maybe or maybe not. Matt (LinuXProX) has agreed to have Jason (FanATIc205) do a follow up review on the Hyper6 using his systems. It’ll give the Hyper6 another chance, and maybe some more feedback to CoolerMaster on how to improve on it for the Hyper7 (or whatever the next version is).
The number one thing I’d suggest is to make the dang thing easier to install. It’s been shown over and over again that people don’t like to remove the motherboard to install something, and people don’t like difficult products. It’s not a complicated concept. I had to give this product our “WTF were they thinking?” award.
