You can figure it out from the pdf manual, compare with Aurora. The core has two long pads: one with 105 and one with 115. The aurora has two same length 105. I think the core doesn't have this issue.
But imo I strongly recommend you buy from the other brand (you know who) and free your brain.
Its price's about $100 higher but considering the confident it brings, and also the fact that your wallet can afford Suprim X 4090, i don't think it's a big issue for you.
Do your brain a favor and focus on something else. I made a mistake of buying this (see my post above) and now I wasted ~$220 and still have to buy from that other brand. What's worse is the free shipping coupon I had for that other brand was expired and I need to pay $82 for shipping fee, plus waiting time for DHL...I wish I bought from the other brand right from the beginning.
we choose VGA waterblock (and void the warranty, at least in my country) not just to keep the temp "acceptable", sir. We want the best (or at least better) for both aesthetic and performance. In your case, this top mosfet, without touching any part of the block, will have worse temp than stock heatsink, unacceptable. I am very surprised you still sell faulty products like this Aurora.
regarding the broken acrylic (see my post above), although no evidence, I really doubt that it's the courier's fault. The seller packed it very very good, the block was untouched (all seals were intact), shipment was smooth and fast (no stay in warehouse for too long), and there was no significant dent or deform of the carton box when I received the parcel.
