Perhaps if the shield was larger, causing the air to be drawn through a smaller area the original configuration may be of more benefit. Whilst there is no doubt that the Hedgehog provides good cooling, it is provided at a price. With cheaper alternatives such as the Arcticooler costing half the price and with results only a few degrees higher, the hedgehog becomes slightly less attractive. However, for those that consider a few degress to be vital, or intend to use a peltier for additional cooling, the Hedgehog will probably provide them with the best solution. The review unit was kindly provided by the gentlemen at CoolPC .
Flat base provides better option for peltier.
Difficult to install in testbed.
