“Little is not the word for this, it's tiny!! I've managed to drop the temperature of a Pi running PSX games from 53 to 48 degrees c. Inexpensive and will prolong the life of your Pi.”
“Works really well, neatly made & super cheap, but good quality! Like all raspberry pi stuff...amazingly reasonable in price and endless applications that it can be utilised for. I have used my with retropie. Loved it so much have bought for numerous friends birthdays.”
