Your technique has to be better than mine because I used an iron, a suction desoldering station and a flux pen. However, after multiple attempts throughout the day, I finally succeeded a short while ago. I am not sure what is wrong with my technique. > > Getting the part out once unsoldered was in my case a bit tricky once or twice > because of the daugthercard sitting next having a 220uF/16V KMC part on the > daugthercard blocking the 4700uF/10V from the above, but it was eventually > doable with some manoeuvre; their position WRT each other seems to vary a > bit between individual H7826s and from your photo I infer you have one where > this won't be a problem.

In my case I have not actually tried powering it on yet, I really wanted to clean it up first as I am sure some of the bits off the heatsinks were likely to create some shorts and I am pretty sure some of these capacitors have leaked. By the way I just noticed a 15uF/25V one next to the fan connector. It isn't one of the SXF ones as far as I can tell, do you recall replacing it? Regards Rob
