Case modded Vali? Succinct answer - not worth the effort. To fix a non problem. I just figured I'd cool her down in case I later wanted to stack something on top. And I have a milling machine.
Having some convenient Type K probes in my hand from some Patsburg & Mustang chip temp measurements - and a warm Vali - I opened her up and pasted down a thermocouple with some Kapton tape. 110.7F, open air stabilized, with Blues Traveler, into DT-770 Pro 250 ohm.
I added another set of vent holes, following the same pattern, with a #4 centering drill on my milling machine.
I measured again, once with kapton blocking the new holes (forgot the un-milled before shot) and once after. Only 1F to 1.5F degree or so difference after letting the temps stabilize. 110.7 tube open air; 109 closed one set of holes; 108 two sets of holes.
I think some low/side and/or bottom holes would allow some real convection and that might do more. There's obvious black anti-vibration stuff on the PCB edge(s) I didn't want to disturb. Didn't figure it'd do or be worth additional effort.
Naturally some pics.
