Plate quenching variations: Anyone try big heat sinks?

I had this thought about keeping the plates cool/cold right before quenching a blade. Take a large freezer pack and sandwich it between the plates. Remove it right before you put the blade in.

I have a chest type freezer out in my shop and have put the plates in before and in between quenching a few times. I don't see any difference in the final product between the chilled plate and room temperature plate quenches.
 
Sorry for the hijack but can anybody piont me to a link that fully explains the plate quench process. When I search there are far too many threads that just mention it without explaining. I think I understand what is going on but want to be sure.
back to your regularly scheduled thread.....
 
Has anyone tried using heatsinks for plate quenching yet?

We started cleaning out one of the storage rooms at work and I was able to grab a pair of aluminum heatsinks that are 8 1/2" along the fins, and 9 1/2" wide. The baseplate is 1/2" thick. The total height of the baseplate and fins is 4 1/2".

If someone would like to try them out, send me an e-mail with your mailing address. With the house renovations, it will be quite a while before I will get to try them out.

With the height of the fins, it should be possible to mount a couple of fans on the ends of the heatsinks. This would cool them down pretty quick. From the thermal testing that I have done, it takes only a few minutes for the temperature to drop significantly once the heat source is removed. I may also be able to dig up some appropriate fans as we clean up more.
