TEMP folder on a different drive?

[spinjector]

I'd like to move my Temp-folders to a different drive.

Is there any reason I shouldn't/couldn't point all of these to "D:\Temp"...?

TMP=C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp

TEMP=C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\Environment\TMP

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\Environment\TEMP

Is there a risk of file name conflicts?

In general, no, but be careful if "interesting" behavior occurs installing a random update or software package. There have been, for example, Windows updates in the past that fail if %TEMP% doesn't resolve to a specific (the default) location. It's been awhile, but it does happen. Assuming you're willing to troubleshoot that if it does (and temporarily "fix" it if that is the problem), you should be fine.
