Will waterblock be enough?

I am going to be taking apart my W/C loop here soon to test for a computer case short and see if that is causing issues on my PCI-E lane and not allowing my second TITAN to be detected..

My question is - do I ABSOLUTELY have to put the stock heatsink back on or do you guys think the waterblock itself will be enough to keep my gpu from being destroy? Obviously I am not going to play any games or anything - the only thing I would do is hook everything up and go into the bios to see if the second gpu is detected or not.

Thanks for your help!
 
You think your watercooling loop is causing your pc to short? How so

No its not the loop. I had posted the issue below a few days ago and came to the conclusion that the case must be shorting out the motherboard.. at least that is my best guess..

Hey guys.. I have been beating my head over this issue for a while now - figured its time to get you experts involved.

This is my system:

Asus Maximus V Formula **latest bios**
i5-3770k stock clocks
GTX TITAN x2 w/ EK XXL blocks
Seasonic 1250w GOLD PSU


So.. I had this system installed an a Fractal Define R2 case and it worked perfectly. I wasn't getting great temps on my WC setup in that case, so I went one bigger and moved everything to an Define R2 XL and added more rad space. Ever since the switch, I have not been able to get my second gpu to work - it is not even detected in the motherboard BIOS - not detected in device manager, not detected by GPU-Z, nothing.

Here is what I have tried:

Tested both GPU's in the first slot and both work just fine.
Updated latest bios on motherboard
Updated Nvidia drivers
Tested both GPU's on the second slot - the computer boots up and Windows boots up, but no video.
swapped the cables around on the gpu's to see if the psu might be faulty or anything - top slot card works no matter what combination of cables I install on it.

Here's the kicker:

I went out and bought another Maximus V Formula. Updated its bios to the latest. rebuilt the WC loop, re-installed latest Nvidia drivers, nothing. Still not detected in BIOS, nothing. I don't think its a seating issue. Why? Because that is what I thought was the issue before - so I spent around 30 min when rebuilding the computer to make sure that they were seated properly. The little latches have come up on both PCI-E slots and locked the cards in - Measured and both cards are the same distance away from the motherboard itself.

Any other ideas? I though that the second PCI-E slot might have pooped out on me in the first motherboard, but the chances of a brand new, second one having the same exact issue is slim.

Thanks again in advance!
 
You can't run it at all unless the stock heat sink is on, or the loop is functional. You will kill that card almost instantly.
 
I guess the only reason I ask is because about 6 mo ago (same setup) my pump died on me and I was still able to use my computer like normal (minus gaming) without my temps going above 50C. Granted there was still water in the loop (though the fans were not running in the case either), but I thought that the amount of copper in the block would at least help dissipate SOME of the heat generated while booting up.

Once again, I wouldn't be doing anything other than going into the motherboard BIOS to see if both GPU's are detected outside of the case.
 
I suppose you could do it quickly, get the room nice and cold before hand. If you are only going into the BIOS then you should be able to get away with.

I would keep my hand on the waterblock and power button, if it starts to feel hot then power down.

I live in New England - its 10F outside. Should be good!
 
It's really not wise to run the card without some cooling mechanism. Will it absolutely kill it right away to do so? Maybe not. I suppose it's a risk though.

Yeah so open the window in the room for about 10mins before and whilst you do it.

Waterblocks are large lumps of copper.

I don't even know if you can kill GPUs with temps anymore, they should just throttle.

I know you can run Intel CPUs with no heatsink fine.
 
No way man don't risk it. I don't know about the GPUs but when I go into the BIOS on my computer my CPU is running pretty much full blast lol.
 
You don't have to remove your motherboard entirely from the case. Just move it away from the tray and make sure everything that touches it is non-conductive. Assuming you aren't running hard tubing, you can keep your loop intact and running.

Yeah this is going to be a bit tough to pull off but I can probably try this.

The big issue is that I need to be able to connect the GPU's to the motherboard. My current problem is that the second GPU is not being detected in the second slot (where it ran perfectly in my other case) so the only thing I can think of is that the case is shorting it out somewhere. It will be interesting to see if I can lift the motherboard off the stands (including the gpu's) and somehow test this.

The reason your fan goes full blast is because that is what the motherboard bios is telling it to do. Not because of temps.

The other guy did make a good point that all gpu's will throttle down after they hit a certain threshold anyways, so it might be ok. I will try to remove it from the mobo tray by itself first and see what I can do from there.
 
I've done what you're proposing a few times, usually to change a setting in bios or windows. You just have to be careful and keep a check on the block temperature. They heat up pretty quick once you get into windows.
 
it will run a few mins before it over heats i sorthof played 10 mins before noticing my pump was accidently disconected....


MAKE SURE you have a fan directly on it tho...

it can be any type of fan even floor fan. but please have air in it . to sorth of help lol

Do a quick test and get out
 
Find a way to fill your GPU water blocks and cap them off. The water should provide enough additional mass to absorb the heat for a few minutes while you are in the BIOS.
