Hello, I need an external radiator

[crusty]

Hi,

I'm looking for an cpu cooler with an external radiator for my threadripper pro workstation (sTR5).

The eiswand 360 CPU looks appropriate but the cooler block is too small for the cpu, are there any other options that come with a larger cooler block that I should consider first?

My alternative would be to buy an AIO cooler and extend the pipework to suit.

Thanks

John

Hi,

XPX Pro CPU cooler will fit well on Threadripper. You can ad it on the Eisstation instead of the XP³ cooler. That is not a problem. IF you want an internal AIO, any Eisbaer Pro AIO will fit.

Thanks Eddy,

It seems a bit of a waste to throw away the XP3 cooler that comes with the eisstation kit but that's probably the best option.

I'll have a look at the Pro AIO to see how complex it would be to convert to be an external radiator anyway.

Another option would be an external Nova station with feet and then an internal expansion tank with pump and cooling around everything with normal hoses. This would be a very effective cooling system, but would also involve some tinkering and costs.

Or you could use the Eisbaer Extreme for external use, but then you'd have to hose to the inside again.

Another question. What's the problem with an internal radiator? So the normal AIO?

Just no space inside the chassis to mount a radiator at all, does the block on the eisbaer extreme completely cover the threadripper pro? It looks too small (but could just be a dodgy photo).

Also, can you purchase extension pipes with quick releases on each end? That would be ideal.

The XPX Pro covers the entire core of the Threadripper. We also use the cooler with the same base for server customers. You don't have to worry about that.
We have Extension Tubes, but i think they could be maybe to short?

Hi Eddy,

Isn't the eisbaer extreme fitted with an XPX cooler rather than an XPX Pro? Other than that, this system looks perfect, the extension pipes should be long enough if I replace both the ones on the block and the radiator.

Thanks again.

 

[Eddy]

You're right about the Eisbaer Extreme. I also expressed myself incorrectly here. The Eisbaer Extreme is also available without a CPU cooler. So radiator with pump and AGB as a single part. Then there are the hoses, the CPU cooler and liquid.
In other words, you could take the non-AIO solution and build your own AIO with the corresponding XPX Pro.

Thanks Eddy, i'll build a system up and see which is better for my purpose (either an Eiswand 360, or an Extreme 280). Do you know what the maximum cooling would be? I.e. could I connect to a 350W cpu and a 4090 gpu? I'm just thinking about future compatibility.

Finally, how do things like import charges and VAT work for delivery to the UK?

Thanks again for all of the help.

 

[Eddy]

350W and a 4090 is too much for only a 280mm radiator. That are around 750W total. Also an Eiswand will have problems with that. To give you a rough idea.
Silent: 120-140W per 120mm fan
Audible so not quiet: 160W per 120mm fan
140mm fans like the Eisbaer Extrem you can put 20W on top.
So you will hardly be able to avoid a Nova station. Roughly speaking, I would use at least 2x 360mm radiators if you want it to be relatively quiet. As a comparison. A normal house heater with a length of 1 metre generates around 600W of waste heat if you turn it up fully.

You have to ask the support directly. I can't tell you anything about this as I don't work in support or deal with orders and shipping costs.

Hi Eddy that's great thanks, I don't have plans to liquid cool the GPU yet, just trying to "future-proof"

How does that work if you add fans on both sides of the radiator? So would an Eisbaer Extreme with 2 extra 140mm fans be sufficient for the processor alone in "silent" mode?

I assume there's no issue from an heater block perspective of the CPU sitting at >90C? As these 7000 TRPs seem to do that.

Thanks for all of the help by the way, I'm learning loads.

If you mount fans on both sides, you will achieve more cooling capacity, but it doesn't make that much of a difference for now that I would recommend it. I would try it as it is for now. If it turns out to be a bit too loud, you can always fit more fans. At least that's the way I would personally go.
I don't think your aim is to brag about the temperatures, you just want to have accurate cooling performance. In my opinion, 2-3°C doesn't really matter in the end.
I won't tell you what temperatures you will actually reach in the end. I would just have to guess. There are too many factors involved, such as ambient temperature, chip quality, with or without overclocking or whether you even optimise the voltage down and much more. I'm not a fan of generalised statements. But you should always end up below 90°C. The advantage of the Trehadripper is that despite the high waste heat, the chip surface area is very large. This means that the heat can be absorbed well over a much larger area than with an AM5 or LGA 1700 CPU, for example. These are sometimes far more difficult to cool because they generate far more waste heat per cm².

My aim is just to stop the CPU from being thermally throttled, with the air heat-sink the current temp goes up to 97/98C - before the power seems to be reduced. I just wanted to make sure that the block/pipe work will not be impacted adversely if the cpu temp. is quite high.

 

[Eddy]

No, you don't need to worry about that. And the temperatures will be much better, I can guarantee you that.
I know, I sometimes write a bit too much

Regarding VAT and custom fees for your country. They will be charged to you, when the parcel will be imported. Either the shipping company will handle it and charge you a small fee for it and when delivering the parcel, you have to pay the fees and the custom fees or you have to go to your local customs to pay there and take your parcel home. For more information, you should contact your local customs.

okay thanks

@Eddy Could I just check the following shopping list before I place an order:

1 x Alphacool Eisbaer Extreme Liquid Cooler Core 280 - Black Edition
1 x Alphacool Eisblock XPX Pro 1U
2 x Alphacool Eisbar GPX extension set (hose and connections)
1 x Alphacool Tec Protect 2 Clear 1000ml
1 x Phobya 4Pin Molex power extension - Black 60cm
1 x Alphacool fan cable 4-pin to 4-pin extension 60cm
1 x Alphacool Apex Thermal grease 4g

Is there anything else that I should add to my order? For instance, does the cpu block include the necessary bracket for the sTR5 socket?

@Vanzin - there seems to be a problem with the website for accepting GB VAT numbers (typically GB123456789 format)?

Thanks

John

 

[Eddy]

That looks good so far. You don't necessarily need the thermal paste. One is included with the Eisbaer. This is either the Subzero or the Apex, although it should actually be the Apex by now. The Subzero would be no worse in practice. Maybe 0.5°C compared to the Apex.
If the hose lengths are sufficient, which I can't estimate for your planned setup, it should fit.

Is that's the case if I purchase just the eisbaer extreme radiator and not the complete kit? and the XPX Pro contains the required bracket for the sTR5 socket?

Now for the wierd question, is it better to buy directly from you or a UK based reseller of your products? As this is a company purchase, I'll be claiming the VAT back anyway so the cost difference is negligible - but you've been really helpful so I'd feel a little guilty if I then went and purchased the items elsewhere.

 

[Eddy]

The XPX Pro comes with a suitable bracket.

Where you buy it is up to you. After all, you're buying our products. If you buy directly from us, we earn more from it, of course. But if you buy it from a reseller, that's good for us in a different way. It's advertising for us at the reseller that customers want our products.
As the UK is not in the EU, you will have to pay customs duties if you order directly from us as we ship from Germany. I would therefore strongly advise you to buy from a local retailer. You definitely don't have to have a guilty conscience. Quite the opposite.
