Will it fit! (Avoid VRM)

[chriscambridge]

Looking to test some CPUs that I have bought using this mobo and cpu cooler.

* Arctic Freezer SP3 4U (CPU Cooler)
* Tyan Tomcat HX S8030 (EPYC 7003 Mobo)

I'm just not 100% sure if the CPU Cooler is going to avoid hitting the mobo VRM.

What do you think?

Hi Chris

I have used (and still am) using Arctic Freezing fans and I found them to be very good, and with great support.

Maybe you need to email them (AF that is) and get the dimensions...so you can see how much clearance there is...

But in general if a fan is designed for a specific socket, the mobo brand has to ensure that any close by components do not exceed certain dimensions...but it doesn't always work out like that

Hey Tim,

I agree, all the Arctic coolers I have used so far have been excellent.

The mobo arrives on Monday so I'll probably just risk it, and if doesn't fit I'll just return the cooler and buy a different version.

The Cooler has good reviews though. At load, on 64c/128t, running a 280w TDP CPU, it runs at 70c.

I think coolers are more designed to avoid memory, but on server mobos the memory is either side of the cpu socket, so isnt really an issue. I am not sure if any of them take into consideration any mobo components that might be in front or behind the cooler, such as this VRM.

I also ordered a (3U) Dynatron A39. This might actually be a better solution as it will probably also cool the VRM.

The socket is 9mm high, the cooler is 151mm high, heatpipes are usually <10mm above the heatsink, the fan comes to the top of the heatsink, the fan is 120mm.

The bottom of the fan should be at least 9 + 151 -10 -120 = 30mm from the PCB.

The VRM heatsink appears to be slightly smaller than the rear panel network socket. Double RJ45 socket heights are ~25mm.

It's going to be close but I'd expect it to fit.

Even if it doesn't, the cooler can be operated with only one fan .... or the fan can be mounted slightly up the heatsink (it only clips in to grooves on the side)

(Nice system )

Thank you Mark.

I am going to finish the build in either a dual socket server or 2x single socket workstations. I think the final result will be pretty impressive.

No problem.

Well you'll never get either of those heatsinks in THAT server setup!

[chriscambridge]

The server comes "barebones" which means it has everything pre-built in (including PSU, mobo, and passive CPU coolers); the only thing you have to install is the CPUs, memory, and drive(s).

This server was pre-ordered a few weeks back, but a couple of days ago I got notified that the server had been delayed by 30 days. This was the main reason I bought the mobo/coolers, just so I could actually test the CPUs before the Ebay 30 day return window closed.

[chriscambridge]

In the end there was loads of space.

[Woodles]

Told you

Weird perspective, first photo made the VRM heatsink look way taller than the connectors and the memory clips. I'm wondering if it is actually a photo or a CAD mock-up ..... or maybe they've had to reduce the height of the fins?

[chriscambridge]

You were right, as per usual Mr Woodles.

Yeah I agree Wbiz, the first image the VRM looked huge.

[chriscambridge]

About to start my new server build.

And this is what it looks like when you log into the BMC, remotely.

And this is what it looks like when you use the BMC to remote into the OS via its KVM browser app.

Jeez....now THAT is some mega-server....256 VCPUs? That's a lot of "muscle".

Hope you'll do more with it than play "Solitaire" or maybe a few levels of "Doom"

And I wonder how noisy that is going to be when it really gets going?

Yeah each processor has 64c/128t, and the server uses around 700w at 99% load.

Its pretty noisy at full load, but less noisy than a portable air con unit.

Doom? Absolutely not, I will only be using this server to play solitaire.

700W isn't too bad I guess...and the heat will be useful in the winter to warm a room !

Doom? Absolutely not, I will only be using this server to play solitaire.

Hey - you can probably run 256 separate Solitaire games all at once... !!

It won't help your chances of winning, but it might stop you being bored for a while !

I like it! A grandmaster of Solitaire in some kind of server simultaneous exhibition of Solitaire. 256 virtual (cpu) opponents is big fry. I have faith in you chris!

Also I understand about the noise of one of those portable air cons, I have one running a lot in the kitchen. Insane that your server is less noisy than that! What OS is that also? Envious, but a bit less so at the fact that it looks hard to maintain to me! I like my computers to be low maintenance, hah.

The new server is running Ubuntu; unfortunately most servers can't run Windows 10/11, due to missing drivers, hence you are stuck with either Linux or Windows Server.
