Meh, I'm one of the worst procrastinators alive today, I'll get a heatsink then spend a week thinking about doing it trying to work out how will be quickest, running out of time and putting it off another day. When you finally get down to it, you're down from cables out, computer out from under desk and mobo out of case in a few minutes, 5 mins to install with thermal paste cleaning/re-applying, then another 5 minutes before I'm turning computer back on.
Having put on a stock intel heatsink for the first time in years outside of the case I wouldn't like to push that hard down on the mobo in a case where it can flex a lot as you push down.
I am getting more behind the whole sealed watercooling unit heatsink thing, not really for performance but because its finally a sane design in terms of space around the socket not being taken up. Decent performance, easier mounting than most tower heatsinks due to low profile and the heat sink/fans being in the way. The daft clips on Thermalright heatsinks do my head in, trying to clip a fan onto one of their big heatsinks, with their crap clips, which just rocks and twists the heatsink around and generally flexing everything.
Antec 620 water jobby coming in at under £40, supposedly very quiet, the bigger brother is very badly priced in the UK though I finally saw a sub £70 price recently, at £60 or just under, like its priced in the US, it would actually be well worth the extra fan control/fan/thicker radiator.
