go look inside of an old computer. there should be one on the processor.
Im aware of those but they dont easily sit on a table if round and cant be easily mounted for a lab rig.

I've been using these for a long time: Green Laser Heat Sink for 12 mm Modules
It's no trouble at all to mount the whole heatsink on a TEC.

i'm also a little confused now.. your title says a heatsink for an aixiz and your main post says you need a heat sink for a tec.

i have one of these
in one of these
with a TEC on bottom

In that case a CPU heatsink should be perfect.. the bigger the better.
trying to get something in this form factor: LASER module GREEN 50mW Sales, Buy LASER module GREEN 50mW Products from alibaba.com

Did you happen to notice the link I posted in post #4? That's pretty much precisely the same as what is in that picture.. better actually since it gives more surface area for dissipation.
great other than i think its too small i tried a 2" cube and it got too hot

a cube has less surface area than a heat sink. so a 2" heat sink will work much better than a 2" cube. i am running a 445 in a small host that has solid hollowed piece of aluminum that my module fits in. it weighs less than an ounce. and can rund for at least 5 mns. i've never had a reason to go longer but i would'nt be afraid to. also note that i am running at 1600ma.

^Well stated Michael!
Those z-bolt heatsinks are about 3.5" square by 1.5" deep..
Maybe there's a misunderstanding here about how the TEC functions.. Ideally you'd want the diode in a heatsink (the mount you have will do perfectly), which you then place on the cold side of the TEC. Then below the hot side of the TEC you need either a thick metal baseplate or another heatsink to dissipate the warmth from the hot side of the TEC, which is why I recommended the CPU sink. So you'll end up with a sandwich with a heatsink on top and another on the bottom.. It will be pretty difficult for you to have everything contained in the form factor you linked to.

I am sandwiching it currently. the link I posted is of the "cube" that is a heat sink that I took off my motherboard. It also has a fan. Rig overheated.

How cool are you trying to keep the diode? You should only need minimal TEC current to keep the diode at a safe temperature.. it sounds to me like you might be driving the TEC too hard, causing it to produce more heat on the hot side.
here are pics of rigs:
CPU heat sink that works: ImageShack® - Online Photo and Video Hosting
mobo sink sink that doesnt(tec and module were moved to cpu rig so they are not in pic ImageShack® - Online Photo and Video Hosting
its connected directly to 5V rail on my CPU's 700 watt power supply give me a few min and ill go get a multimeter connected in the loop
