Like you when i first decided to go on watercooling i was a bit scared, you know water+electric components
, even because most of my components were quite expenssive and i couldnt afford to replace them if i f**ked up bit style, well i could but would take me a few month of course.
My advice is to get familiar with everything, read the guides here on OCN there some good ones on watercooling forum, also there's plenty experienced members that can give you good tips, i thank those who help me out
. My tips are order plenty of tubbing and a few extra fittings, double check your fittings and tubbing size matching. If you go for compression fittings read up on them, dont overtight them you will never get them off again if you need to re-tube or do maintenance to your system.
Also and this is were i f**ck it up royally, take extra care attaching your fans to the rad, is easy done to just grab the wrong size screws and pierce the rad without realise, i found out that the hard way, luckly the place i got my stuff included on my order and installation insurance for a small amount of Â£17 and paid off bacause they send me a replacement straight away and luckly after the accidend put the stock cooler everything was working good.
I already have my rad back and everything is fine now and im very happy i did it for the experiance i had and for the performance on the system.
Good luck tho, have fun
