Hey all,
I recently purchased one of Ronac's Cryos Cooling Bezels and wanted to share my initial impressions about it, especially for those looking at picking one up for themselves.
My disclaimer is as follows: I bought this bezel with my own money, for my own use. All of my "tests" are done without the aid of any measuring devices, so obviously, my impressions are subjective. So here we go…
Fit and Finish: The Bezel I purchased was the HAIII black version; it's a somewhat glossy
finish but not quite as shiny as the 6P HAII glossy black. It's incredible smooth, almost silky to the touch.
The bezel itself appears to have sharp edges when first viewed in pictures, but I was pleasantly surprised to find that it has absolutely no sharp edges whatsoever. Ron has noted in his sales thread that they are tumbled before finish, and it pays off. You can carry this one in your coat pocket and not have to re-line it a week later!
One of the best features is the 2mm overlap where the bezel and host mate; this eliminates any gaps when using this with some of the slightly oversized drop-ins (think Malkoff). The tolerance is very tight; I could not even slip a piece of paper in between the bezel and host once screwed down. Be mindful of the fact that this may also interfere with the clip on a C2 host, so it's clip off is using this rig.
I ordered mine through Oveready and had it finished off with a Pyrex bezel and one of the smooth black bezel rings. Any of the Oveready bezel ring offerings work, so smooth or crenellated, it's up to you. The plain old Surefire plastic ring works as well.
I tried the fit on multiple hosts: The Oveready Moddoolar, 6P, C2, solarforce and it worked with all of them. Same thing with my Malkoff drop-ins, standard Surefire drop-ins, and a bunch of custom Quads… all fit with no gap!!
So how did it work?
2 main points to keep in mind about the design as stated inthe specs:
1. 40% increase in surface area compared to conventional (unfinned) heads,
2. Improves heat dissipation via both convection and radiation.
Can I prove that this is true? No. Do I think this stuff does what it says it does? Heck yeah..
Here's what I did:
I have a VANisledsm 5.6 quad that also happens to be a massive heat generator, so much so, that I have only been able to run it for about 4-5 minutes at a time due to the C2 rig I have it in getting painfully hot. When I run this thing with the stock Z44 bezel, what happens is that the Quad (which has an incredibly tight fit AND arctic silver thermal paste between it and the host), instantly transfers all of that heat right to the host, and to my hand in a hurry. The Bezel itself becomes dangerously hot as well, to the point where if I touch it, it burns.
Now, I'm not claiming that the Cryos bezel gained me hours of runtime here, but it did make a very perceptible difference. What I noticed right away was that instead of a full on transfer of heat to my hand within 2-3 minutes, I instead felt more of a
gradual build up of heat down the battery tube. Now, it still got uncomfortably hot after some time, but not as fast. My tolerable runtime went up by about 2-3 more minutes… which is a lot given the shear amount of light these quads put out. 4-5 minutes vs. about 8 with the Cryos head. It was definitely doing its thing
The other major thing I noticed was that I could touch the bezel, indeed, wrap my hand around it, as the outer parts of the fins were not hot!! Take that flat old bezel!!!
All that and I also believe that with the right set up, say 2x18650, the Cryos bezel will also tenderize meats (Handy for camping).
Seriously, I feel this thing does what it says it can do. I also did some Malkoff M91 runs with it and was also able to hold the bezel in my hand, even with the host being very hot to the touch.
It's also a GREAT looking Bezel, just the right blend of beefy, but not overdone
I like it so much, that I aim to buy more… at least one for every serious quad in my collection and the M91.
Great work Ron!! :thumbsup:

I think that the Cryos head on a 6P body is the Ducks Guts. Thank you Ron!
