Which EK Supremacy jet plate is best for an FX-8350

[Grinder]

Planning on OCing, and the loop consists of 2 290x EK full cover blocks in parallel with bridge edition connector, two 3x120 rads, D5 vario, 1/2ID tubing, EK pump top/res.

*edit* Looks like J1. But I've read other suggestions in various searches...

I say the one that's least restrictive. you've got plenty of rad to do the cooling. let lots of water hit the cores.

Actually, J3 looks the least restrictive. J1 is .8mm thick, J2 1.0mm, J4 0.7mm. J3 is 0.7mm but has a larger slot. At first I thought the measurements were the width of the slot, but it's the thickness. So it seems the plates are used to adjust how flat or concave the block is.

There are some test results here:

It shows that J3 is noticeably better for an overclocked 3770k than J1 and J2. Unfortunately they don't mention what is recommended for AMD there, and the 8 core Visheras make more heat than the 3770k. According to the manual, J4 is for 2011, J3 is an all round great performer, J2 is for 1150/775, and J1 is for AMD and 1366.

I like your thinking regarding flow, but don't want to pick the wrong one and have to drain my loop to change it out. BTW, the block comes with J3 installed.

Luc! Where are you!

*edit* Looking at a ton of testing done by a guy over at XS, J3 was best for 2500k, 3770k, 3930k, while J2 was best for 4770k and J1 for 4930k.

I found some flow data for the different plates, there is only a ~4% difference between the most and least restrictive, 327 l/h vs 340 l/h.

I'm leaning towards J4 now, which is said to be optimized for larger cpus. Manual says it's for 2011. Unlike the other intel chips, at least it has the cores around the outside of the die (and 8350 has them in the corners).
