I would like to thank Bas of spire-coolers for providing us the FridgeRock.
Spire-coolers have a cool amd heat sink fan combo that sports a thermal sensor that controls the fan speed!
First impressions:
The FridgeRock is one big heat sink. In fact it’s larger than my thermalright slk-800! The unit is all aluminum, with a slab of copper on the bottom. This heat sink features 20 CFM to 27 CFM fan, controlled by a thermal sensor attached to the fan. At low temperatures, the fan spins at 3000 rpm. But when things start to get hot, the fan kicks in to overdrive to 4000 rpm. Also included, is a fan guard and a tube of their thermal grease.
Specifications:
Socket A / 370 Cooling kit
Dimensions Heat sink:
12VDC Fan: 78×73×49 mm (l × w × h)
70×70×25mm
Bearing Two Ball bearing
Rated speed 3000 ~ 4000 RPM +/-10%
Rated power 3.60 W
Noise level 27.0 ~ 35.0 dBA
Air flow 20.13 CFM at 3,000 RPM
27.19 CFM at 4,000 RPM
Life hours Two Ball: 70.000

Before installation, I removed the thermal tape that was stuck on the bottom of the heat sink. Why it was there, even though the unit came with thermal grease is beyond me. Removing this stuff is a pain, but I came up with a method that works great.
I.e.: see my article on removing thermal tape.
Applying a thin layer of arctic silver to the CPU core, I started the installation process. As stated before, this is a big heat sink. Some motherboards won’t be able to use it. Check the clearance around your CPU first. I was kind of surprised that the unit had only a one lug retention clip. Their little skivestream heat sink had a very nice 3 lug clip. :/
Test System
AMD XP 2600+ 333 MHz (AIUHB)
Asus A7N8X Deluxe rev 2.0
Corsair PC2700 XMS 512 MEGS
Beantech igloo 7 aluminum case
Maxtor Diamond 9 30 gig harddrive.
To test the unit I used Sandra’s burn in wizard for 30 minutes. I’ve included a few other heat sinks for comparison.
The FridgeRock produced some good temperature numbers. 4 degrees at idle better than the skivestream. And 9 degrees at full load!
If you can fit the unit on your motherboard you might want to consider the FridgeRock.
Pros:
-Good cooling
-Copper core insert
-Comes with a fan guard
-Thermal sensor
Cons:
-single lug clip
-might be to big to install on some motherboards
