1. If looking for quality reviews, youtube is best avoided. reading PCPer and other text based articles and then making videos about what you read isn't all that informative.
2. A $50 air cooler will outperform almost every 2 x 120 AIO and many 3 x 120s on the market.
3. To hit desired price points, AIO vendors generally use cheap aluminum radiators which also succumb to galvanic corrosion after the useful life (18 - 24 months) of the corrosion inhibitors expire) ... this requires the use of extreme speed fans. Pump rate are also inadequate, especially if expanding the loop.
4. The Swiftech H360 is basically a collection of Swiftech's custom loop products pre-assembled at the factory. The pump is easily capable of handling the addition of more radiators and blocks tho with 2 rads and more than 2 blocks id want a dualie like the Swiftech 35x2.
So if it's an AIO that ya want w/o corrosion issues and capability for expansyion, great performance and onlt about twice as loud as an air cooler (H100i is 11 times as loud) ... I have installed a half dozen Swiftechs, I have changed the coolant twice. To make that latter job easier ... I installed a G-1/4 MxM 10mm fitting on th e side port, then a F XF Valve, another MxM and finally a G-1/4 Tee F x F x F tee (branch up) with plugs on top and remaining side port..
When you need to add coolant, take off the plug at top of tee, put a thick book under front of case, open valve a bit and sloely fill thru tee top port ... when ya want to drain, take of the side port on the tee , connect a G-1.3 M x compression fitting attached to 3 feet of flex tubing, open valve and drain.
Some references on aluminum rads (if upou can't click links, copy paste into url window then delete the 2 spaces after the // ... I didnt wanna clog the post with big blocks.
