But it also voids your warranty on these units that are not really all that reliable to begin with.
Also, I'm told that lapping the cooler isn't important as making sure that the base is not concave, so make sure that you lap it properly.

In my experience, lapping has not been necessary; on my GTX 480, I can increase the voltage to the maximum possible, and it doesn't get much above 70 degrees, without lapping.

Ya, pretty certain it would void. If you trust your unit and feel its going to last or don't care if it craps out in a year or two then why not. My max low was 20c-ish but lapping dropped me down to 17c max lows and load temps regardless will always be excellent with the mod, its just going to be more excellent if you can scrap a few more degrees off biggrin.gif

To answer the question imo, yes it makes enough of a difference if you care about that type of thing to warrant the time. If your up and running I would not suggest ripping everything down to lap but if its sitting there and you've got the time....... To others, perhaps not. Do what your comfortable doing, the mod does not have to be destructive in anyway but there is some more wiggle room to make it better depending on how much of a risk your willing to take.

On most*. It is okay to lap Corsair AIO and keep your warranty. As long as you don't do any damage to the plastic housing or cause any leaks.

I think it's more trouble than it's worth with these coolers, because I don't want to lap it, then have to RMA it, or not be able to RMA it because they don't like lapping, so I would want to run it for a couple weeks or a month to make sure that it won't be a waste of time, but then I would have to tear apart everything to lap it, so it's not worth the trouble for me.

Agreed, good advice- don't mod till tested and proven good.

I'm never really confident in these closed loop coolers, though; they don't have the best reputation among the community.

Flashed my gpu to 1000mhz core and 2000mhz shader and 4660ghz memory with a vcore voltage at 1.125 i have a Asus 560ti direct cu2 run at standard 820mhz core 1660mhz shader clocks 4200mhz memory anyway my fan speed is high lol run at 95% all the time as im good at bios overclocking but couldnt work out how to flash a fan profile only edit min max speed . Idle i get 25c max is 63c -65c so as you can see im not doing to bad benchmarks shot right up wink.gif but more to the point its nosy and ive been thinking about doing this mod i have VRM coolers on my model but the memory is not cooled by the gpu heatsink and have no heatsinks of there own so do you think i would get away with just adding the cpu watercooler also do u think temps and overclock would get better with this type of watercooling unit thanks all

hello all~
i'm back with my 3rd time using "the mod"
this time on a gtx 660 ti ftw signature 2 (rather large name lol)


link for anyone interested in the card:
http://www.newegg.com/Product/Product.aspx?Item=N82E16814130837&nm_mc=TEMC-RMA-Approvel&cm_mmc=TEMC-RMA-Approvel-_-Content-_-text-_-
on a side note, i highly recommend this card; it outperforms both my previous 570 and 550 sli and gives smooth framrates in pretty much all the big title games, specifically skyrim with all the modded textures, butter, etc.


anyways, gaming temperatures on stock cooler peaked in the high 40's and low 50's (in open case as you'll see in pictures)
so the cooling was more than sufficient. but since i had a H70 and an H60 laying around from my old 550's i decided i may as well have some fun.
it was a relatively quick process, i'll skim pretty quickly over it, pm me if want an in-detail walkthrough on how to secure an h60

i attatched a corsair H60 to the card, with zip ties inserted through holes on the pump and screws~


it's alittle hard to see (sorry blurry image) but after removing the pump cover, i threaded the zip tie through the screw hole.


then i secured it to the card


and plugged it in


sorry my setup is rather messy at the moment confusedsmiley.png i took it all out of my case cuz i was having problems with my previous graphics cards tongue.gif

now i was hoping to fit the 660 sig 2 shroud back on, but since i actually want to keep the warranty this time, i decided it would be a bad idea to chop up the fan supports. tongue.gif

gaming temps never top 40c, so it's about a 10 degree difference!

hope u guys enjoy.

cheers~

hi dougko,

a liquid cpu cooler would definitely bring your core temperatures down.

vrm temperatures shouldn't be a problem as long as you have a fan blowing on them.

first post on this page has a good setup:
http://www.overclock.net/t/1203528/official-nvidia-gpu-mod-club-aka-the-mod/470#post_16736695

also, it depends if your case has good airflow. if you could fill out the rigbuilder, and add a few pics of your setup, that would be a great help thumb.gif
hope this helps some!

cheers~
