Overclockers Online reviews 2 budget coolers from Spire, the VertiCool II and the DiamondCool II.  While neither will win prizes for extreme cooling, they are certainly powerful enough to use in a normally clocked PC.
“So how do we classify these new coolers from Spire? Considering that the cost for either HSF is ~$32 according to PriceWatch, I think that one word sums it up: balance. Both units run cooler than the stock equipment while producing less noise, which is something that we can all respect. But in the end, the VertiCool II is the better performer, and thus, the better cooler.”
