    3u chinese server cases

    Nope, far too much effort. The amount was not actually that much, so in the end it taught me an important lesson without too much cost.

    3u chinese server cases

    I just wanted to share my experience of Aliexpress; it is great for finding products at low prices, but if you have issues and have to return the product, or get refunds, or get Aliexpress staff involved to uphold normal selling practices then it can be somewhat of a minefield. In terms of the...

    3u chinese server cases

    I used to use Aliexpress, but when a load of fans turned up all smashed and broken, and the seller offered me a 5% refund, and Aliexpress agreed I stopped using them. I mentioned that I had paid for postage, and therefore under normally selling guarantees, the seller should pay for return...

    Gigabyte HPC Server cooling question?

    Oh that does make doing a review kind of difficult :eek: Thanks for the heads up on the DELL (and Inspur) 4U GPU servers; I wasn't actually aware of them. Its actually quite interesting to see how all the different players approach the 4U 8-10 GPU server approach; and from what I see only...

    Gigabyte HPC Server cooling question?

    Thanks that's really useful; I hadn't realized just how much air these Gigabyte midplane fans pull in. I did wonder about that server you reviewed (G481-s80) as it seems to have a very similar chassis to this and another Gigabyte server (G482-Z51). What made me think twice though is the server...

    Gigabyte HPC Server cooling question?

    (I edited my previous reply) I think I have solved this now.. A quick search on that heatsink part number brings up the fact that it is also used on the Gigabyte W291-Z00. https://www.servethehome.com/gigabyte-w291-z00-review-amd-epyc-gpu-server/ A quick search for images of that Tower...

    Gigabyte HPC Server cooling question?

    There are also 4 fans on the back of the chassis. Basically all the fans are pumping air into or extracing out of, the 10 GPUs. I think the way this server may work (in terms of CPU cooling) is by using either 4U active (fan based) heatsinks, or flat/horizontal active (fan based) heatsinks; I...

    Gigabyte HPC Server cooling question?

    There are no fans behind the heatsinks eg the fan wall is in front of the CPUs, not behind it. This is what I meant when I mentioned "excluding heat sinks"; obviously like you say passive heat sinks need air flow.

    Gigabyte HPC Server cooling question?

    Gigabyte G482-Z50 Does anyone know, or could find out (as I think this server is pre-release), exactly how the following Gigabyte HPC server cools its CPUs? (excluding heat sinks) As you can see there are no front chassis fans, only fans behind the GPUs and at the back of the Chassis; hence my...

    Anyone know diff between E5-2699-V4 and E5-2699C-V4 ?

    Thanks; I agree the C version is rubbish.. however the E5-2699P-V4 version looks pretty nice. 3 GHz Base, 3.6 GHz Turbo Especially if you compare that to the normal 99V4.

    Anyone know diff between E5-2699-V4 and E5-2699C-V4 ?

    Thanks for your reply and sharing this, its not coming up in Google when I do a search so that is very useful. So am I right in thinking that when the Turbo is listed (for the 99) as: 6/6/6/6/6/6/6/6/6/6/ 6/6/6/6/7/8/9/10/11/12/ 14/14 It means: It will run 22 cores Turbo at, base freq (2.2)...

    Anyone know diff between E5-2699-V4 and E5-2699C-V4 ?

    So I just spoke to a seller of these and he indicated that these are non-retail OEM E5-2699V4's that were produced for Sun Microsystems, hence why there is not information being listed about them.

    SOLD: 1U vented blank rack panels

    I would have been interested as I am going to be buying some of these soon, however I am based in the UK so It doesnt really make sense financially as I can buy them for around $10 (£7) each over here. I was hoping maybe you had quite a few so I could try to offset the shipping cost.
