Fanner Group/Spire FD08025B1ME4 System Cooler Review
MSRP: $6.93 U.S.

Let me begin by thanking Bas and Jeroen from Fanner Group for making this review possible. Please visit for more great products!

By now you should know Spire. We looked at the Spire FalconRock II HSF a couple of reviews ago and we were mighty impressed. Spire is a part of Fanner Group. They produce quality products that work, for a very affordable price.

Today we examine their system cooling offering. The Spire FD08025B1ME4 System Cooler. Also know as a PCI Slot cooler, Spire is hard at work making sure that these will lower your case temperatures. In theory slot coolers are meant to lower case temperatures. Will the Spire succeed in doing so? Let's find out!


  • Dimensions: 90x80x10 mm (L x W x H)
  • Bearing: Sleeve-or Ball bearing
  • Rated speed: 4500 RPM
  • Noise level: 25.6 dBA
  • Air flow: 16.0 CFM at 4500 RPM
  • Current: A 0.12 A
  • Life Hours Sleeve: 30.000 / Ball: 50.000
  • Connector: 4 Pin, power supply
  • Application: Any free ISA or PCI slot in the PC case.

We have the Ball bearing to evaluate

As you can see, the package is well done and gives the idea of a cool winter mountain. Hence the point of the cooler is to make your computer run cooler.

Here we have the system cooler. Notice how Spire has elected to utilize a plastic type fan guard.

Here we see the back of the unit. Notice the fin design? This cooler is rated at pulling 16 CFM's of air. However, we would have liked if the fin design were open as possible for fewer obstruction of hot air escaping. Nothing a mod can't do...:)

Adding this to your existing setup will increase noise. Listening to the cooler, it grasps a small low-tone whine. This is due to the fan rotating at around 4500RPM. This may not be good for people who would like to maintain quiet. It added some noise to my setup.

Installation and Testing

Not really much you can say for installation. Just unscrew the provided screw and place the unit into an empty PCI slot at the back of your computer. I prefer you shift it down at least 3 slots below your AGP card for optimal heat dissipation. We want it to suck out as much hot air as possible from the AGP card and lower part of the case as a whole.

One problem that may happen when installing is that the System Cooler might be a tight fit on one's computer. When I installing it, the cooler was tight between the motherboard's PCI Slots. This could pose a possible problem for others.

Testing consisted of monitoring system temperatures, for any decrease. The ambient room temp was around 22-23c with four fans all running inside the Chenming Aluminum case.

System Bed

  • AMD ATHLON XP 1900+
  • ABIT NV7-133R
  • ATI RADEON 9700 PRO 128MB
  • LG 32X10X40X CDRW

The results

The CPU cooler in use is the Spire FalconRock II HSF that was reviewed here. We will compile the before temperatures from the review and compare them to the temperatures we have conducted with the Spire System Cooler installed.

  • Before:
  • Idle: System Temp: 21c, CPU Temp: 42c
  • LOAD: Toast 5 Min: System Temp: 25c, CPU Temp: 53c
  • LOAD: UT 2003 DEMO (1 Hour): System Temp: 24c, CPU Temp: 48.50c


  • After:
  • Idle: System Temp: 19c, CPU Temp: 42c
  • LOAD: Toast 5 Min: System Temp: 22c, CPU Temp: 52c
  • LOAD: UT 2003 (1 Hour): System Temp: 22c, CPU Temp: 49.50c

The cooler does actually do what it says. In theory, case (system) temperatures are supposed to be decreased. As you can see by the results, the idle system temperatures receives a reduction of 2c. The Toast test received a welcome decrease of system temperatures by 3c. Lastly, in the UT 2003 test, the system cooler decreased system temps once again, this time by 2c.


There you have it. The Spire System Cooler does work. Not much like I would have expected, but it does the job well. Every bit helps. I just expected a little more.

NOTE: No two systems are identical, so you may experience different results, depending on the variables faced.


I give the Spire System Cooler an...



+ Brought down system temperatures

+ Build Quality

+ Very affordable

- Fan obstruction (plastic grill, rear grill)

- Some may not like more noise
