Thermaltake Silent Boost HSF Review


Looking for a K7 cooler that can offer you performance and something unique? Looking for a silent solution but don’t want to lose the performance? Today the Thermaltake Silent Boost takes the stand providing the cooling world with something new.

Thermaltake was nice enough to ship us a sample in the usual corrugated TT sample box. The Thermaltake Silent Boost packaging is inviting and is well done. The back of the box features the coolers specifications. The Thermaltake Silent Boost is displayed predominately in the front. You notice right away a new fan design.

The Thermaltake Silent Boost is an all-copper cooler and one that looks very good. Thermaltake did an excellent job in the design and construction of the copper heatsink. 41 fins are spaced evenly to provide maximum heat dissipation and allow cool air to cool the heatsink. The heatsink is covered with a fan shroud and has the Silent Boost name engraved.

What you get with the Silent Boost are:

  • Thermaltake Silent Boost HSF
  • Instructions
  • Dow Corning Thermal Compound

The fan is unique and one of a kind. The 80mm fan has slits around the fan to provide multi-directional fan. What this does is allow cool air to not only circulate from the top down, but from the side of the fan as well. It works folks. When I placed my finger on the side of the fan I could feel sucking air in. The fan spins around 2450RPM and pulls around 27.5CFM @ 21dBA.

  • Here is a movie clip of the fan in action. It’s relatively close to the camera’s microphone btw that's why you may think it's loud. Disregarding the movie, I feel the fan is a tad louder than the 21dBA stated.  Maybe around 25dBA.  The fan thus is relatively quiet.

The Thermaltake Silent Boost has a flat base. There are some machine marks present and could be done in a better finish but for the most part it is flat.


Testing will consist of running the Thermaltake Silent Boost through tests after 72 hours of the Arctic Silver Ceramique setting in. Test system here.

I would like to mention that the Thermaltake Silent Boost features a 3-prong clip and was very easy to clip. It has the slug where the screwdriver falls plus the other lug where there is no clip is already held tight to the base.  This helps the overall clipping very easy.


Results are taken from SOLTEK Hardware Monitor V2.04. Load is 5 minutes of Toast 2. Ambient temperatures range from 21.23c.

Silent Boost (K7) Results
Idle (30 mins): 38c
Load: UT 2003 (1-Hour): 43-44c
Toast 2 (5 mins): 45c

As you can see the Thermaltake Silent Boost performs very well and is not loud. In comparison to the Thermaltake Volcano 11+, the Slient Boost is not loud to achieve nice results.


The Thermaltake Silent Boost performs great while not being loud and noisy. The packaging and construction is top notch and is better in everyway in my opinion that the Thermaltake Volcano 11+.

I rate the Thermaltake Silent Boost a…


Pros and Cons

+ Excellent construction
+ Unique fan
+ Relatively quiet
+ 3-prong clip
+ Performance-noise ratio
- Some may find it pricey

I would like to thank Thermaltake for making this review possible and telling you about this fine cooler.
