Is there a Quark 125B thermal problem?

Well, im stuck in a bind! They should have used small HeatPipes to conduct the heat from the top set of FET's to the bottom ones and case. Why would it make such a difference cooling only the bottom ones?? This is weird.

I THink i might just lap the bottom of the case and use A.S. to conduct heat away into the upper Alum chassis brace on my vehicle...

I live in Canada, so even in the summer, i would only drive the car max 25 degrees Celsius, and i don't drive that hard either. So maybe just doing what i will do will be good enough?

Do you guys that have dont the mod, do you get noticeable longer runtime?

Really, the stock setup should be "good enough". If it thermals, then Quark support should be notified. These types of mods are done to make it run more reliably, so any mods are bound to make improvements if done right.

I haven't noticed any runtime differences, and I can't see how that would be affects. What it does do is allow you to run much longer (just about indefinitely) without worrying about whether it will thermal. If that's what you mean by runtime, then yes, it runs MUCH longer. :)

k, well im just going to run it for now with a good HS of my own design, or i'll just integrate the HS into the upper chassis, to reduce weight, and i'm sure it would work even better than a separate HS.

Then, if i ever want to do the Alumina mod later down the road... and perhaps I might even mount liquid cooling blocks to each side of the FET's for extreme cooling, and then run the liquid along the aluminum chassis to cool it... PRETTY COOL
