THE RAYSTORM 750 EX280
I will start with the 280mm radiator because i compared it with a few others i have here and i have to say i really liked the craftsmanship by the guys over at XSPC.
This radiator is 36mm thick, 320mm long and 143mm wide so as you can see from the above pictures it's not only longer and wider but it's also thicker than your average 240mm radiator.
Another thing i found interesting is that it actually uses twice as many fins as the radiators i have here (smaller of course but higher density) and that should increase its cooling efficiency.
You will need to remove the caps to install the bundled fittings (suggest using an spanner to do that).
The XSPC logo is engraved on both sides of the radiator.
The reservoir/pump combo is very convenient although i do understand that many people might not want to use two 5.25" bays for that (XSPC has them covered with their solutions too).
You can check the current coolant level from a small clear plastic section at the front of the reservoir (naturally the fill cap is placed at the top).
The reservoir/pump model is also indicated on a small sticker on the right side.
At the rear we see the in/out fitting holes, a small rubber area where you can place the bundled LED and what seems to be a cap for when you wish to empty the reservoir.
XSPC bundles two 140mm XINRUILIAN fans with the Raystorm 750 EX280 kit which can reach speeds up to 1350RPM and output up to 73.92CFM of airflow with 29dBA of noise.
The CPU waterblock may not be all copper (XSPC makes a full-copper one) but it does feature an all-copper base (56x56x3mm in size) that has a mirror like finish.
The bundled LEDs are for the reservoir/pump (single) and the waterblock (dual) but unfortunately they are not as bright as we'd like them to be.
