Liquid Cooling R9 290X

[ZARIFF]

Hello guys, I have a Gigabyte R9 290X Windforce gpu and it's really really hot. Bought it of with 200$ from my country and it's brand new, It was a clearance sale and they're gonna replace it with the RX 480 if anything happens to the gpu. Now, my point is that, which gpu liquid cooling solution will be the best cheap method for the non-reference R9 290X. It hits 45c on idle and 90 on full load. My case is optimized with Cooler Master Case fans, (JetFlo, SIckleFo, XtraFlo), and have them mounted on all 5 slots and I use a core I7 4770 with a Hyper 414S. My casing is a bit stupid, Thermaltake MId tower casing but it's not that bad either. Are water coolers effective on the 290x ? I live in a tropical country where the sun is always scorching hot. And i'll buy the cooling solution from Amazon so please give me the links as well. Thanks a lot !
