I'm pretty sure the SP3 and TR4 is the same physical socket so Dynatron does have a cooler:https://www.dynatron.co/product-page/a28Or the loud one:https://www.dynatron.co/product-page/a31For the A28 I would recommend having 25mm thick fan options for increased pressure and possible high rpm industry fans :-)However, that means a CPU cooler hieght of 52,5mm which adds a lot to the volume (had to do it in my own case).With a 2500 rpm 25mm thick fan I would still suspect some thermal throttle :-/
