Improvised and easy to make heatsink mod using a M18 Bolt / Nut which is exactly 27mm by width and fits exactly from top of the chip to the top of the shielding. You dont even need to drill a hole into the nut but use thermal glue for example. Or just paste. The fit is thight enough so the nut wont move. But you shouldnt shake the scope without at leats glue ;)
I overclocked my skope now and it runs stable so far for over an hour.


Of course Hantek shouldnt have cheaped out on some small heatsinks or added a very slow FAN. Or at least the connector for a FAN would have been good. I know they try to save up every penny, but that shouldnt be done on thermal design. My Hantek didnt hang up so far but I wanted to overclock it, as it feels very sluggish sadly. Its a great scope but slow. First it was hanning up on one overclocked setting but now runs fine. (10% overclocking)
