Crashman :
Not so odd when you consider it's the Editor's Choice CPU cooler. Our Hyper 212 EVO hasn't been around for years...but I did consider the three-heat-pipe issue when I decided not to just pitch the Pro 3 from the comparison. I also thought of the direction of the core vs the direction of curvature of the Pro 3's base.
Right I knew where you were coming from with the gammaxx 400 since it was an award winner. I just figured with the popularity of the 212 evo and the fact it was cooler master's previous flagship budget cooler it would have been included to show what gains if any cooler master has made in 5 years. The masterair pro 3 and 4 look like modern updates to the tx3 and 212 +/evo.
I couldn't tell if anything had actually been updated on these like ram clearance compatibility or anything since the 212 and tx3 or if they're more or less a more expensive direct replacement model. It's still pretty early with comparisons of these new coolers but other reviews don't seem to pit them against the 212 evo either.
It does look like the pro 3 offset the heat pipes a bit for better ram clearance but the pro 4 didn't. They updated the fans, that may be a plus. The downside is that so many places already have the 212 evo and if it performs the same as the pro 4 there's little justification in the price. The 212 evo has been steadily selling for $25-30 usd, $45 is a hard sell. If the evo's were priced at $45 they'd likely be collecting dust on a shelf, outshone by less expensive and equally as capable coolers. $45 is within striking distance of their own hyper 612 v2, raijintek ereboss, a couple decent reeven coolers or the dark rock 3.
They do have a nice appeal with the black cover facing out vs the bare aluminum fins of the older models but at this point it seems like they're competing with their own products from 5yrs ago and the old products are beating the new models on price/performance. I was hoping they would have made significant improvements for a 50%+ cost increase. The name may be more in line with their 'master' series but they could have just as easily named the pro 4 the 212 evo v2 or 212 ++. Even if they stop production of the 212 evo and let current stock dry up the competition's already undercutting them.
