we'll see when i get the thermal cam in my hand, we'll see... I only need to figure out how to take pictures so that metal case would not block my "heat view".. I mean, I can't take pics when cover is taken off.. then the air will not tunnel through.. and taking pics with cover on I cant see single component heat.. I can only see heat spots on case.. maybe that is enough though...
Thermal cam won't particularly help. Just look at core temps at a fixed ambient and fan rpm.

as I think I mentioned before, "my design" appear to push out less air, and hashing temp is the same (although reaching same temp takes more time) = less rpm needed to cool to same temp, but that's not all, shutting down miner and starting again show that modified single has cooler starting temp = it must be more efficient as air goes thru single and does not hassel around-up-n-down (also less noisy), now i order to see if everything is cooled and compare original design with my design I was thinkig of takeking thermal images where both are in front of me on the table, and outside (to get bigger contrast of cold/warm).

Non steady state conditions tell you nothing about the cooling capacity of the system, too many things going on.

Let us keep it simple. Does the unit have temperature sensors? Are they showing better cooling? Are you getting better hashrate?

If you are good enough.

I'd say temperature is the same and power usage is some 2-4W lower

Steady state typically means when everything in is the same as everything going out. In this case, when the heatsink gets to a constant, stable temperature, effective steady state is reached.

here you go

both on the same pic:


close-up with same temp scale:

so, I'm happy and end of story. going to modify second one too.

Hi eestimees

From the picture, the "mod" looks to be made from metal. I don't have a metal sheet nor the tools to bend one if I had it in the first place, but I'm interested in modding the Single.

Do you (guys) think that a hard cardboard could do the trick? Is it safe to use cardboard in the first place? aka it doesn't catch fire from the heat.

What about venting the top of the case and making both end fans pull air in?

Yes, it has been cut out from old miditower case. The heat on top is not so high, but i would not reccon paper or cardboard anyway.. For me it is too much risk.

I though that too but did not want to cut or drill the original case of single... But if you do that some air shrouds are reccomended to push amd pull the air the right way and quietly.

So what you are saying is BFL designed it wrong?

I find that hard to believe.

I replaced the 2 x 92mm fans on the heatsinks to  2 x 120mm Gentle Typhoon AP-15s. Runs naked on my desk with no sound at all @ 60C.
