4. Top - 1 x 20 or 2 x 12 or 2 x 14cm fans (Optional)
Quick google suggests the case has 2x120mm fans spaces at the top. Looking at the motherboard tray I would suggest there should be enough clearance:

Thats great thanks mate, Would this be a good option for cooling?

The main reason is just to have more cooler airflow going through the case to keep temps down
) but only with the higher end stuff. If you want this as a first-step that isn't too scary, it's probably a good way to go - as long as you accept that it may not last for 10 years and isn't going to be as good as it gets. If you've got other reasons, tell us what they are and we'll try to help.VKleita is mostly correct (sorry). If you tell us what you're trying to achieve, we can tell you if this is a good way to do it. It could be that you just want to take a first, small step towards watercooling. That's where VKleita isn't entirely correct: a lot of the stuff people here buy/build/want isn't, strictly-speaking, necessary but if they want it or it looks cool, why not? If it makes you happy, why not.
AIOs aren't the most impressive coolers you're going to find. In fact, some of the more advanced air coolers may even beat them. Ultimately, watercooling gives you the best cooling for the amount of noise produced (excluding the silly stuff like liquid nitrogen) but only with the higher end stuff.

It'll also give you a taste of the full works - hopefully a good taste! VKleita and Snips are right that a low-end watercooling setup will be beaten by a high-end air-cooled setup in terms of cooling. It's definitely going to be a step up from a stock Intel heatsink though!Hi all
I have a Aerocool Xpredator X3 case and on my MOBO i have the stock Intel CPU fan, Will a H100i Corsair fit my case and will i need to order some Thermal paste with it?
Thank you
