The H50 isn't a miracle cpu cooler as it's painted out to be. The radiator and sides should feel warm if it's doing its job, dissipating heat. I think you have a poor contact between the heatsink and the cpu. Try reapplying thermal compound properly and see if that makes a difference. You didn't list your CPU (not in specs either) so I can't compare apples to oranges, but my Core i7-860 (at stock) hits the lower 50s while doing Folding@Home.
First off...Aigo... that wasn't the mouth we put those in... (JK JK just had too!)
Anyway. The H50 hasn't ever been billed as a "miracle" cooler... But yeah, you're right, radiator feeling warm is a *good* thing. The H50 is however competitive with air coolers at the price, and takes up MUCH less room in your case. The H50 isn't going to match or outperform a high end Noctua, but it also doesn't block your ram slots and look ridiculous...lol.
Anyway, 60c under load is fine, however for stock the H50 should be able to keep it in the lower 50's depending on your room temp
Make sure the cooler is tightened down on all 4 sides. You used the stock thermal paste on the H50, right? (It's VERY good). Is your fan blowing air from *outside* the case in, like corsair recommends? If yes, try adding another fan in a pull config.. so you have two on it. That is good for 4-6C drop in temps. But anyway, 60c under load is fine. I think you can get better out of it for stock, but meh. My rig under a nice custom water cooling setup sometimes gets into the 60's depending on room temps, and I consider that to be very good, i7's run super hot (then again i'm putting 1.425vcore and 1.367vtt through it at 4.4ghz lol).
