I really don't get what you're asking.

Will it now?
Last I recall, XP, Vista and 7 can be installed on a partition where another OS has previously been installed.
It will be a surprise if Vista or XP can be installed on top of Windows 7 without formatting? Can they?

On top? No.
But they can be installed onto the same partition. Of course, they will "remove" the other OS. Its files will still remain, along with everything else, but you cannot use the old OS anymore.
So yes, you can install without formatting.
EDIT:
Actually, I never tried installing Vista on a 7 partition, but I do believe it can work.
Right, well even if we pretend for a second that the OP didn't say "Anyway, gonna check with ubuntu," it really doesn't make it any less sensible to back up and do a clean installation of the above operating systems is significantly more sensible than installing over the old operating system and being left with a very sloppy file system. Vista (and I believe 7) is particularly faulty with this because of it's terrible Windows Side-By-Side folders.
So to answer your original question... nobody said he "has to" reformat... but why shouldn't he? To me, it's like you're telling a guy with a key to a door that he doesn't "have to" use the key... he can always just kick down the door.

From what I remember it doesn't remove the other OS, really... it just renames everything to [folder].old and let's it be.

Ignoring anything else, there's still the issue of the 200Mb WinRE primary partition created by Windows 7 that will definitely show during WinXP or Vista installation.
I haven't myself either. I'm more skeptical however.Actually, I never tried installing Vista on a 7 partition, but I do believe it can work.
In any case, due to the WinRE partition, it's not even advisable one just installs Vista or XP on top of Windows 7 just like that. A little housecleaning, like repartitioning to remove the WinRE partition is advisable, and necessarily forces a format.

That was my point
I haven't heard not seen of any partition like that, though.
Still, I don't think it's going to cause troubles, is it?
Pretty sure this was with reference to the link to a thread about Toshibas overheating from a ubuntu forum, which neither thing actually had anything to do with ubunu.

Yes, I think you're right, though I don't really see the need to check overheating issues after he already realized his issue was the operating system. Regardless, it doesn't change my point. Backup and clean install always works better than installing over. To me that's like painting over paint without putting a primer first.

That seems more like a myth to me. I can't count how many times I've installed over old Windows installations without wiping the partition first.
I thought y'all were talking about an upgrade, but I guess there is no upgrade from windows 7! Except linux
I put new OS installs over old ones without formatting the partition fairly regularly (inc. XP*), and have never had a problem. I don't see what difference "formatting the drive" will make unless you zero out the data too (aka, a low level format), which can take HOURS.
Unless you are changing the filesystem type, of course. Then you need to format the partition as a new type.
That said, doing a format wouldn't hurt either.
*tho for all I know XP does do a format.

Well it's probably because you've never experienced an upgrade from an OS where there is no upgrade path. There is no in-place upgrade to windows 7 from XP, for instance.
Without specific information a clean install is always safer simply because it will always work. It should be painless anyway. Data you don't have two copies of is data you don't care about.
You get to choose if you want to format or not. Or at least for XP pro, never tried home so can't comment on that one.
