What did you get incorrectly the first time?
If you are spending $100, you are better off going with an XSPC kit (starting around $130 to $189 or more with pump upgrade) or just going with a good air cooler.
I was sent a Rasa CPU block with a single rad and a different pump. I don't remember the exact model number of each part/kit. I was planning on spending $150 on the kit I originally mentioned. Will that work better for me than a high end air cooler?
