  1. that's why i said nirvana are on spotify, not nirvana is on spotify
  2. thanks we might all be audiophiles, but some have larger files
  3. 'scuse iggerance, but what's dtaf ? acronyms are okay if you recognise them, but i'm lost
  4. for the pi fans, this looks a winner https://www.banggood.com/pointsmall/Armor-Aluminum-Alloy-Case-Gold-Protective-Shell-without-Fan-Version-for-Raspberry-Pi-4-Model-B-Only-p-1559054.html?cur_warehouse=CN
  5. i too have arctic silver on all my cpus (and gpus too, where it matters), but there's plenty of recent competitors that can top it current top dog is allegedly thermal grizzly kryonaut (if price is unimportant, i guess) https://www.gamingscan.com/best-thermal-paste/ i have a tube of liquid metal that i have left untouched due to oh&s concerns 😨
  6. already linked to arctic alumina in my earlier post - it's non-conductive
  7. silicon is more an insulator than a conductor of heat thermal tape is the win but the guys above suggesting a metal case are on the money, especially if there is a conductive thermal bond from the case to the cpu my little khadas tone board is in a hefty aluminium case with minimal air flow., but the case itself allows any collected internal heat to dissipate very effectively
  8. would benefit from holes in the side of the case above the board, because convective cooling would pull more air in from the side(s) to passively rise out of the case, than would fit past the "block" provided by the motherboard along the edge as shown by the red arrows plan b would be to macguyver a bigger 'sink over the cpu - what's holding in on ? because a touch of epoxy with arctic silver paste will be more efficient, and as it looks like you have height to spare, simply increasing the height of the fins could almost double your radiant area so, the gold one was recovered from a very old video card, and is 1.5" square by 9/16" high (imperialist measure) - council pickup was my source, but if you really want to go bunta, zalman made awesome and beautiful passive sinks for northbridge coolers on motherboards back in the day, but these guys are seriously tall, although the base of the beautiful pale blue fan is smaller than the gold one cheap and easy sources (slow delivery) https://www.aliexpress.com/item/32998838853.html https://www.aliexpress.com/item/32950514537.html copper is more efficient than aluminium; this seems perfect https://www.aliexpress.com/item/4000110224085.html but you'll need either thermal tape or an adhesive : https://www.pccasegear.com/products/4712/sekisui-5760-thermal-tape - a wise choice https://www.computeronline.com.au/products.php?C_ID=1&S_ID=259&PROD=43538 - once that's used, it's there for eternity ! hope that helps
  9. that stuff should probably be recognised as carcinogenic these days - it often has asbestos impurity from the mining sources (long story, but google johnson & johnson + talc) you can but "microballoons" from surfboard makers (air filled tiny glass beads), but sawdust is the most sensible and obvious thing to add to glue - balsa dust works fine too - it's a hardwood
  10. i remember auditioning it after the salesman suggested a pioneer sa series (like most of my school mates owned) was not as the best choice at that price point he was absolutely right
  11. i had the luxman L2 as my first amp now i'm all nostalgic
  12. audiovisual glue, of course gorilla glue is relatively cheap, but it expands quite impressively as it goes off, so small amount only required
  13. ha ! when i had my protracted "sabbatical with malignancy" i trained up my microsurgical skills by variously wiring connectors on micro drones to flash their firmware for acrobatics, and in my best effort, substituted a new momentary switch to an otherwise crapped out pixel 5 which i still use soldering is easy (once you can).... but desoldering without the good gear is hideously frustrating
