Which CPU Water Block Do I Use?

I have two water blocks to choose from when I do my rebuild.

My old EK Supremacy CSQ. Been running that block for 8 years now :eek:

. But still fits latest LGA 1200 socket, so saw no reason to change.

Or

The newer Phanteks Glacier C350IP.

Had planned to use the Phanteks on my girlfriends new PC build, but might give her the EK block instead if the Phanteks is better.

If your EK block is still good then keep using it. I would probably change all of the O rings as they are 8+ years old now. They are cheap enough on Ebay and I believe the main one is 57 x 2mm EPDM70 and the one under the jet plate is 28.3 x 1.78mm NBR 70. There is little point in changing it from a performance perspective as all of the top blocks within a couple of degrees of each other anyway.

Thanks. Never thought to change the O-rings! I've found the smaller jet plane size, but can only get the larger 57x2 in Viton not EPDM. I think that should be OK though.
I'll probably wait and measure them.

I've taken a closer look at the block and can see some minor cracks appearing in the acrylic. I have similar ones in my bay res which have been there for years without issue.
Should I be concerned? I can upload some photos if needs be?

Nitrile O-rings will be ok and that's what I used on mine. This will do the job. The micro cracks are around the threads for the fittings yes? Probably nothing to worry about and I had them on mine and it was fine. You used to be able to get replacement tops for them but I don't know if they are still sold.

Yeah, they look to be propagating from the connections. Thanks.
