This link is to newegg and specifically ones that are compatible. Gives you a wide price range depending on your budget. You can narrow the search with more specifics using the advanced section of the search. I only based the search on the 755 socket type, and not the size limitations because I didn't see an option for that. Be careful because I did see a 1-2 around 95 mm which won't work if you only have space for 92(obviously?).
Out of that list the one that looked best to me:
One of the reviews talks about bringing the temps from 70 to 46 C under 100% load. Obviously that can't be an exact measurement but it seems like that user had good success.
You could also look and see if stock fans are sold on Intel's site. I looked a little and didn't see anything but maybe you will have more luck. Sorry I only looked for a few minutes(I have class in like 20 minutes so don't have the time to put to much effort in on Intel's site)
Thanks for putting effort into this, I'll check that link out!
95mm should still fit. I have about 100mm width and height wise, and around 130mm length wise (how far the heatsink sticks out).
