Question about buying used XSPC cooler

[DCNo07]

Hey guys,
I recently added a second gfx card to my computer and my temps are getting a little high on the top card (about 75C).. That is not at full load and only after about a half hour of gaming in a relatively cool room (about 70F). I read the water cooling sticky and came to the conclusion that the best setup would this kit then adding a second 120mm rad and looping it to through my gpu's. I am trying to save some money so I found someone selling this kit used for $100(I think the retail is about $190).
I have a few questions -
1. Would that kit be sufficient for the setup I'm going for?
2. Would I need to buy a different pump in order to loop the CPU and GPU's? Or would that one be ok?
3. With a used setup should I buy a new pump regardless?
4. Is $100 a good deal for that kit?

I should also mention I don't plan on doing any crazy OC'ing with my GPU's (I most likely won't change the stock clock since they are factory OC). I just like my temps to be low.

Thanks for the help guys!

What is your system specs ? And what is the kit the guy is selling ? 120mm, 240mm, 360mm, 420mm ?

The Rad is 240mm. Sorry did that link not work? It's this kit - http://www.frozencpu.com/products/24811/ex-wat-312/XSPC_Raystorm_RX240_V3_Extreme_Universal_CPU_Water_Cooling_Kit_New_Rev_4_Pump_Included_w_Free_Dead-Water.html

Pretty much I would only be using the Rad, fittings and the cpu block from this kit. I read up on that pump and apparently it is extremely weak and the screw for the led in the back is prone to leaking... Not something I want to risk. The guy said he would let it go for $90.

It will be okay for your system, i'd get a second 240mm, 360mm for the gpus instead of a 120 though. And did you consider you blocks and fittings ? Plan everything before purchase. If you need help say so

Would it be ok to run the GPU's through the top 240mm rad and the CPU through the 120mm rad at the back of the case? I would have them all running in a loop. CPU won't be OC'd over 4ghz. I have looked into GPU blocks and unfortunately I haven't been able to find a universal block that will fit with SLI. So I guess I am looking at $120 per block.

You maybe able to get with a 120mm for the cpu and 240 for gpu but you have to get thick ones, the one that comes witht the kit is not thick, it will not be enough for two cards in sli. (I did that and temps were the same as with air cooling). Use the stock 240 for cpu and get a 360mm for the GPUs.
