“This set is individually sized and you really can't go wrong with where to place them. A word of advice, you may need to use tweezers to place the smaller ones as they can be a bit fiddly. Otherwise a good piece of kit that seems to work well.”
“Nice item, fits perfectly in my Pi4B. Noticeably cooler, although not by much. If I was doing more than running retro games I'd also buy a fan, without question.”
