Replacing component in loop - need to change fittings / hose or not?

[Michaeljcox24]

On Wednesday when it get's delivered, all being well I'll be swapping a 690 for a 980 with XSPC block.

I didn't want to have to strip the whole rig down, and ideally I'd like to just open the drain tap, and catch all the coolant in a bucket. Loosen the fittings up, take the card out, put new card in, etc etc. Re use coolant.

Because I've had compression fittings on the hose, is it good practice to replace the hose or not? Or will it be good to go? I've only had the loop running since late August, so it's not time to do the annual maintenance yet.

Also, when do the o rings in the compression fittings begin to wear?

btw, I don't have quick disconnects, and wont be buying any because the next purchase will be a new board and cpu so will be probably stripping the whole lot down.

I have a 240 in the base of the case with a drain point coming out of the side. It was something I never put in the old loop, which caused a massive headache when I came to change it. I was hoping to just take the plug out and reuse the coolant because it's only been in the loop 4 ish months.

Changed it over today, and the 980 is stable at 1520. Process was relatively pain free, apart from a slug of coolant stuck behind an airlock that was going into the GPU

The new GPU beats the 690 max overclock for max overclock. I added 2000 points onto my Firestrike score. Worthy purchase, because I desperately needed the VRAM.
