You can see my machine below, and I was wondering what the best cpu cooler would be for it. I was looking at the Spire Thermax Eclipse II, but my God that looks giant, and I haven't the smallest idea of whether or not it would fit (155x132x125mm) If it would, I would probably go for that, so please tell me if it could fit my case. (Noise doesn't really matter much to me, my 3 120mm fans and gtx 275 at 75% already make plenty noise)
If it wouldn't fit, what cpu cooler would be best worth investing? I plan on overclocking it, the actual amount dependent on my results with the new cooler.
I can't find my case online at the moment, but the dimensions are:
200mm wide x 480mm long x 430mm high.
Next to the CPU cooler is a side fan that takes off about 35mm in width. I will gladly remove that fan if I will get better temps without it (my system has no problem staying cool with an overclock, just the CPU)
The case dimensions minus the side fan determines what size cooler you can fit in. A factor to consider is the turbulence created by having the side fan too close to the cooler. I don't think that it would be a good idea to remove the side fan; will make the cooling worse.
A good way to check would be to use a wood ruler and measure the distance from the CPU heat spreader to the edge of the case, and deduct the case fan width. This would give you the max dimension of the cooler. For Megahalem or the Hyper 212 this dimension should be about 160mm.
