Koolance VID-LN2-V2 - dissapointment at first glance (literally)

[tiborrr]

I've bought a Koolance VID-LN2-V2 pot trough one of the official german reseller as a reserve since I normaly use my old copper pots or LittleDevil's GFX-R1 unit, but I have never seen such a piss poor quality machining being done on any cooling unit. While the unit is perfect on the outside, the machining and coating quality on the inside are just sad. I believe the pictures speak for themselves. Metal shavings? No thanks



I have yet to test it with LN2, I hope it performs better than it looks

[Mean Machine]

That'll just give you more surface area. Shouldn't affect performance negatively, even though it does look like .

[T_M]

They very clearly have not optimised the internals either.
Those holes shouldnt be near the GPU faces

[Blue Storm]

what a disgusting

[der8auer]

Yea this is really bad quality :O

[jesperme]

Does all gpu tubes from koolance look like that? It looks like . better to stick to our old forum friends for GOOD quality.

[BeepBeep2]

Wow, that's horrible. But look at their CPU pot:

[e-Killer]

i have the V1 and there is no internals (at least you have one) but the perfomance is not bad (i have it in GTX 280 and is very good) the bad thing about mine is the sujection ( bends like butter) .

I,d make sure its all back to room temp before you start taking any screws out
That is unless you like to drill and tap

Forgot to report back. I have tested it with acetone and dry ice and it's leaking! Acetone almost completely ate my lacquer insulation. Don't know about the LN2 just yet, I will test it in the following week as I have 295GTX dual-PCB here ready to go. Something tells me the end results will be much the same

Jesus that is horrible coming from a vid-428 I wonder what it looks like inside . Like jesperme said I am sure it looks like internally but performs decently aside from the leaking...

[ScottALot]

hehe keep that filled with LN2 or dry ice and you'll get temps near your liquid cooled rig haha

[tiborrr]

It wasn't so bad on dry ice, really. It held GTX470 @ -58°C* loaded at 1070/1220 with 1.25Vgpu with dry ice and acetone. But the thing leaks, what the hell?

* Measured with blue K-type probe which shows -174°C submerged in LN2.

[cdolphin]

That is unimpressive.
Send it back/talk to them? I mean seriously, what is this?
Looks like someone tried to use an endmill to drill a hole >.<

[tiborrr]

Well, the pot leaks nitrogen aswell And the saddest part is: IT DOES NOT FIT ON GTX 295! The GPUs are clearly not lined up, the difference is about 1.5mm and whoever engineered this pot did not take that into consideration. I had to remove the I/O bracket in order to mount the pot and only to realize the internal SLI bridges have no contact with their sockets. The result is flickering of the screen in SLI mode.

I ruined a perfectly good card because no one at Koolance seem to have tested the pot before it got shipped out to the market

[s0lid]

Well the 295 shouldn't be ruined since the flexible printed circuit bridges are removable

[dinos22]

What a friggin disaster

[zalbard]

I've seen better homemade ones... Consider RMAing it. Might be a poor machining work, but it definitely shouldn't leak.
Btw, there is something up with the pics in the OP today...

[tiborrr]

So, anyone thinks I could get this RMAed? No use in having a leaky pot that doesn't fit the one card I primarily bought it for.

P.S.: Card survived, I had to fiddle around with the bridges until it started working again. Yaay

[zalbard]

Yeah, RMA it.
