EK thermal pads are the best imo, you can get them in 0.5mm, 1mm and 1.5mm thickness.
I had the same issue as TaKeN once with some rather solid blue thermals pads I bought, the EK ones are soft and squishy so even if you get them too thick they'll press down and won't put up any resistance.
Glad to see I'm not the only one
Are the EK ones identical to the stock pads? very squishy and easy to remove?
