As for the difference, that has come from several sources here at OCN as well as other sources that I trust to know what they are talking about. I don't have links to those results since I don't use those types of cooling systems. I see some FanBoys touting how much better the H70 is than the H50, but I've yet to see any tests done by a reputable source using the same fans that didn't show the H50 to match or exceed the H70 in cooling performance.
I guess that makes me a "fanboy" then. I've seen several reviews showing the H70 out performing the H50, but you don't have to take my word for it:
Under heavy loads the H70 outperforms the H50, especially if everything is equal (fans, lapping, cases, installation). I've seen this result over and over.
The H50 is a great cooler and I think it's hard to beat for the price, but the H70 IS better. The proof is out there. Look for more evidence by Googling H60 reviews. Several of them compare the H50, H60, and H70. I got my H70 for $80, which is a great price. I've seen the H50 going for $49. At that price the H50 is hard to pass up.
Although you may find the noise generated by a dual 120mm fan loud, if you set it up well you generate almost no noise at idle and it only ramps up as heat increases. I did this by using Scythe PWM fans and a fan splitter I made, allowing the CPU header on the motherboard to control the fan speeds while providing power for those two fans from the PSU. This does add expense to a build, but personally I found it worth the extra cost. Also there is the pitch of the noise to consider. A smaller fan as found on most air coolers makes a higher pitched noise, which I personally find very annoying. A cooler using one or two 120mm fans (which both internal water coolers AND some high end air coolers use) has a lower frequency, less annoying operating noise. Lastly, there is the sheer weight of the cooler. The H70 performs on par with the best air coolers, but it doesn't hang off of the CPU and motherboard but rather the case itself. Again, personally, I find this to be an advantage. Lastly, I also like the look of the internal water coolers, and I like the look of the opened up central area of the case provided by the water block.
However in this particular case, I think OolerTheInventor got the very best H50 anyone has ever gotten, it's premodded and free. Can't get any better than that. AND, with that added reservoir it likely DOES outperform an H70.
