Cooler Master Hyper 6 HSF Cooler Master Hyper 6 HSF: We take look at Cooler Master's latest HSF, and test it against some of the best air coolers we have.
Date: May 19, 2004

Installation - Pentium 4

For the P4, we repeated the motherboard removal process and installed the universal retention bracket.

Place the backplate under the motherboard, and screw in the retention bracket with the four included Phillips screws to complete the process.

The CPU and heatsink are next, and use the two clips to secure the heatsink. The fan follows, and you're done.

Test Setup - Athlon 64 @ 2195MHz

MSI K8T Neo: Athlon 64 (10.5x209) @ 1.95v, 2 x 512MB Kingston HyperX PC4000 (2.5-3-3-6), AIW Radeon 9800 Pro, 120GB Western Digital SE 8MB Cache, Windows XP SP1, ATI Catalyst 4.4.

Going up against the Hyper 6 for our Athlon 64 tests will be the Thermalright SLK-948U. Both coolers will be using the Cooler Master A8025-30CB-3AA-PI 80mm fan included with the Hyper 6. We will also present numbers with two Cooler Master fans (Blow/Suck config). We will be testing both low and high fan speeds for the noise and performance conscious readers. Arctic Silver 5 was the thermal paste used for all the tests.

To load up the system, we ran Prime95 run for 30 minutes, with Folding @ Home running in the background. Ambient room temperature is maintained at ~23°C/74°F.

Temperatures did not take long to stabilize (about eight minutes) at their max temperatures, so at the 10 minute mark, readings were measured at 2 minute intervals, added, then divided by 10 to attain the average temperature.

Load Temperatures (°C)

Heatsink, Fan (Speed)
Temperature (°C)
Hyper 6, 80mm fan (Low)
Hyper 6, 80mm fan (High)
Hyper 6, 2 x 80mm fan (High)
SLK-948U, 80mm fan (High)

The Hyper 6 puts out some great numbers with a dual fan setup, but you do pay for it with the noise. The Cooler Master fans aren't terribly loud though, at least when compared to the Vantec Tornado, but this setup is not something I'm comfortable with noise-wise.

At the single, low fan speed setup, the Hyper 6 is outperformed by 0.5°C by the SLK-478U, which is running at high speed. When the speeds are matched, we can see that the Hyper 6 is the clear winner here.

Test Setup - Pentium 4 3000MHz

ASUS P4C800-E: Pentium 4 2.C (12x250) @ 1.8v, 2 x 512MB Kingston HyperX PC4000 (2.5-3-3-6), AIW Radeon 9800 Pro, 120GB Western Digital SE 8MB Cache, Windows XP SP1, ATI Catalyst 4.4.

All testing methodology is identical to our Athlon 64 tests. Competing coolers will be the Swiftech MCX478-V and Aerocool HT-101. Temperatures with two Cooler Master fans will be given on both the Hyper 6 and the HT-101.

Load Temperatures (°C)

Heatsink, Fan
Temperature (°C)
Hyper 6, 80mm fan (Low)
Hyper 6, 80mm fan (High)
Hyper 6, 2 x 80mm fan (High)
MCX478-V, 80mm fan (High)
HT-101, 80mm fan (Low)
HT-101, 2 x 80mm fan (High)

With a single or dual setup, the Hyper 6 walks away from the other coolers in this roundup.

Dual Fan Configuration Temperatures (°C) - Pentium 4

Heatsink, Config on P4 @ 3GHz
Temperature (°C)
Hyper 6, Blow/Suck
Hyper 6, Blow/Blow

If dual fans are in the plans, you're much better off using a blow/suck configuration for a couple reasons. Performance is certainly improved, as the air moves in a direct path rather than just blowing randomly, and the setup is slightly quieter in this configuration.

Final Words

Performance was simply amazing for an air cooler, rivaling some of our water setups. Using a low speed fan nets some very good numbers, but the Hyper 6 really shines with a couple high speed fans.

The build quality is excellent, and being 100% copper and aluminum, the Hyper 6 has a sturdy feel to it. Everything is included, from the retention bracket to the thermal paste. The variable speed fan includes a fan controller where you can manually adjust the fan speed.

Although the large size of the cooler helps the performance, it can also pose issues for some people depending on their motherboards and cases. Low profile cases need not apply, as well as cases with custom duct mods. The dual fan issues we've mentioned earlier is something to keep in mind regardless of the platform.

Another problem we found was despite the tapered bottom of the heatsink (for clearance reasons), the Hyper 6 will not fit on an Albatron 875P because of the motherboard's Northbridge heatsink interfering with the setup. Although I was not able to test it on more motherboards, I am fairly certain that any motherboard with a large Northbridge (NB) heatsink within the vicinity of the socket will run into the same problem. You can shave the NB heatsink if necessary, but out of the box, this was the problem we ran into.

If your motherboard shares a similar layout as the ones we've used today, the Hyper 6 is certainly one cooler that deserves to be on the top of your shopping list. Being a universal heatsink, it can easily be swapped between platforms, saving you money if you make a switch. A quick search on Google shows the Hyper 6 in the 40$ USD range, and considering the package, this is quite a good deal.

Pros: Great performance, excellent build quality.

Cons: Large size can pose problems with some setups.

Bottom Line: Cooler Master put together the best performing air cooler we've seen thus far. Although heatpipes are not new here, their implementation of the technology was well done. Being the largest heatsink we've tested probably had a lot to do with it as well.
