As title, spent an awful time fitting a corsair h55 and corsair n780 bracket to one on my 780Tis today. The instructions for both were absolutely appalling, but that's another story.

I'm pretty certain it's set up as it should be and making contact with the GPU die properly.
The connector is connected on the n780 bracket and GPU fan is spinning, and the 3 pin power connector from the pump is connected to a socket on my motherboard.

I ran a quick heaven bench and the GPU temp slowly crept up and up til the 80's at which point I quit. It's obvioulsy not working.

Ideas, quick??? How do I tell if the pump is working properly?

Does the rad get hot? If the pump wasn't working it wouldn't get warm at all and your GPU temp would climb quickly.

I'd take the whole lot of and check the contact, especially as you had such a hard time fitting.
 
Make sure the 3 pin connector of the pump is connected to a fanheader of the motherboard that gets full power, and is not on fanspeed smart control on bios setting.

If the cooler is working, your 780Ti's temp shouldn't be above 60C or there about under load.
 
Cheers fellas. I'm Making some progress...... The fan attached to the rad wasn't spinning at all I discovered! Switched that connector to a different one and it worked fine, and re ran heaven and it didn't go over 45 degrees!! I think I'm making progress :-) Still some tinkering to do though, as the fan attached to the rad is too loud now imo.

Also, the whole fan header thing is confusing. I have power settings for fan set to 'adaptive' or whatever in the BIOS to keep my cpu fan down so I may have to tinker with bios settings again.

100% sure I've sorted it now, thank christ! Pump is deffo working as rad gets hot, and with the fan now running it's keeping GPU temps well down :-) Still more testing to do but I'm sure it's fine now.

But.... the fan it waaaaaaaay too loud attached to the H55 rad. What's the best way to slow it down/ make it adaptive???

I use a fan controller for my fans on my H55, works a treat.
 
Corsair stock fans are absolutely bloody appallingly loud.

What you want is a Noiseblocker Bionic mate. I used a 600 RPM on my 480 Lightning, never went over 48c in Valley (for nearly two hours).

Edit. I'm now using a H55 on a Titan Black, same sort of temps as you (minus the noise, I'm using an Aerocool fan).

I think the stock fan on the H55 is a 1700rpm fan with 3pin connector?

You might be able to connect that to chassis/power fan header, and set the fanspeed to standard or silent to reduce the speed. Hower do make sure the pump is not connect to the same type of header, or when you set the fanspeed profile to standard/silent, it would cut down the power to the pump as well.

Woah, what case is that!?
 
Just a wee update. Swapped out the included fan with the Corsair H55 for my antec rear case fan that has 3 manual volt settings. Got it running on the slowest speed and the card hasn't broken 55 degrees under full load, in an SLI config in a messy case, with the bottom 780Ti still using a reference cooler.

With the fan on medium speed it stays under 50 degrees, but it's still a bit loud so keeping on low. Pretty happy with that for now! Panic over.

Problem now is, now I know how to install it all properly, I want / need another h55 and corsair n780 bracket for my other 780Ti. This bottom card is now hitting 83 degrees and is obviously limiting the water cooled card. I discovered today that 780Ti's cannot be clocked independently using Afterburner etc. Apparently it's a known quirk/ feature of the 780Ti in SLI.

It was a bit of an experiment/ gamble getting the one h55 and bracket to be honest but it's paid off. Might wait til I get my new system build and case though to get a second and do it properly.

thats not a quirk of 780ti's thats what all gpus are like, they need to be overclocked the same otherwise they will both run at the lowest clocked cards speed.

i stumbled upon this sight about a year ago and now i am in the same boat as you... i want to mod everything. shame i picked a gpu that cant be AIO cooled though (well it can but it would be with that god awful looking NZXT thing).

Seems to be some confusion about independently overclocking in SLI. See this thread for example http://forums.evga.com/Overclocking-2x-780-Ti39s-independently-in-SLI-m2115455.aspx

And that info does bear out to my experience and personal memory too - I had different 670s in SLI before my 780Ti's and they could operate at different clock speeds. My 780Tis don't/ won't.
 
Oh. I thought I had read on here some where that you need to have your cards in the same clocks like i said. ATM it doesn't affect me as I don't plan on going sli xfire in the near future.
 
I was almost right. From my quick glance at that thread I took that it is only Kepler that was ever able to be separately overclocked or took advantage of that separate ocing?
