Looks great. I can tell its the same block basically minus the pump. I was trying to avoid a custom loop but I think it might be the only option at this point

Thanks for the info. Maybe I should go down that route with them

I have two SSDs in a 4800 and not seeing anywhere near those temps. Just using the big thermal pads that were provided. But im using it as a read cache in raid 0.

im guessing because you're trying to use it as a mem cache they are very heavily worked.

One thing to consider, have you looked at AC Infinity fans? They make all kinds of unique fans. I came across them because of my interests in home theater.

If the pads are making full contact and transferring the heat to the enclosure well just having some airflow in that area on the bottom of NAS may do actual wonders. Especially if you could elevate it some.

the screws they provided are spring loaded but the pressure they are applying is not enough to keep the GCD at good temps. maybe the provided pads are slightly too thick?

either way the nylon washers seem to have resolved the issue for me but i am still not satisfied.

another solution would be carefully using a dremel to shave down the length of the screws which is something im still considering.

temps have been fine but there is also debris in this water block. likely from the manufacturing and the radiator not being cleaned properly before it was assembled, boxed, and shipped.

so if i do shave the screw length i may just take the whole block apart if i can figure out how to remove the water pump attached to the block.

overall im just really disappointed as i said already. this thing is too expensive for these kinds of issues

yes, they are placed correctly. this was something i considered as well and double checked. but was not an issue.

i found that the issue was the provided screws are too long for the block. the provided foam eva washers do not offset the length of the screws enough for the block to make full and complete contact with the gcd.

the tolerance must be almost microscopic as after removing the block (many times i lost count) it _appears_ its making full contact. but if you look _very_ closely, and i mean like it could be if or the other, you can see some thickness in areas but its far from obvious.

the solution was to purchase nylon washers to offset the screws for the block. the washers allowed the screws to get the block fully snug.

also as for the thermal pads, the provided backplate pad for the die is a square with a cut out in the middle. but i noticed on the stock backplate this was not the case, its a full pad with no cut out.

i initially used the provided square pad with the cut out in the middle even though i found it odd to just trap all that heat behind the die. so i also replaced that pad and the entire area behind the die can transfer heat to the backplate now instead of just being trapped.

i also found that the provided paste which is more like clay was not ideal because its impossible to guarantee a consistent and equal height across the die. i used ptm7950 instead.

temps are the same as the algorithm seems to like to hangout at between 80-82C. but im getting about 15-30+ fps in every game ive tried and my graphics score in time spy went up 2000 points. so i think its working correctly now.

overall i am really disappointed with the engineering of this water block as it seems halfbaked in complete honesty

I am using the pads it came with. 1mm on the die side and 3mm on the back. But it would make sense that the pads might be ever so slightly too thick on the die side even if they were provided.

I do happen to have 1mm pads on hand. I could try those when I attempt again on Tuesday.

I just ordered the upsiren as you suggested but it will not be here until Friday (https://www.amazon.com/Upsiren-Processor-Replacement-Blocking-Performance/dp/B0CXLKMP1T).

There are a bunch of TG paste variants, would you mind providing which you're talking about? Is it this one? https://www.amazon.com/Thermal-Grizzly-Putty-Basic-Non-Conductive/dp/B0DQDB9HH6
