Will this fit a HIS 4670 Ice Q? The stock fan/heatsink needs to be replaced.

I purchased it for an EVGA GeForce 6200 AGP 8X Video Card, but it did not fit this card so I returned it. Check the specs in detail to make sure it fits your card. Visit your VGA card makers site and the Logisys site to double check. Good Luck!

I'm looking for a small fan to replace my secutiy system dvr it is a 2 pin 40mm square, would this work as a replacement?

I have an older ATI RADEON 9600 video card and it fits perfectly . The fan is 50mm in diameter and the push pins are 55mm on center. So you need 50mm clearance for this fan to fit and If the pin location match at 55mm it shoul match. The plug is a standard 2 pin fan plug .
