Hey all, I am putting together a water cooled system and have been unable to find a water block for the
XFX GTX 275 Part No.: GX-275X-AHFF. Hoping someone here has found a block for said card.
As an extra note i have ordered http://www.koolance.com/water-cool [...] uct_id=866 and http://www.koolance.com/water-cool [...] uct_id=818, neither fit.

I have also contacted XFX and they dont have an aftermarket compatability list, and was unable to find one at http://ekwaterblocks.com.

Even if no one knows of a block but knows of a place i could look that would be great to.

I have posted this in cooler and heatsinks per Shadow703793's suggestion.

PLEASE DO NOT get a Koolance. They are not top quality.


Get the MCW60: http://www.swiftnets.com/products/mcw60-R.asp
Buy: http://www.jab-tech.com/Swiftech-M [...] -4271.html


Get some RAM/Mosfet sinks (DO NOT FORGET THESE!) and you are set! Btw, what pump,rad,etc? Post this in the "Cooler and Heatsinks" section. The only 4-5 WCer (including me) are there only.


and to answer your question the block and radiator i picked up are

Thank you for the 2 links but neither appear to have what i am looking for, i really may need to just go with shadows suggestion and go with separate gpu and video ram coolers.

if this explains anything this is a picture of the card i am working with, to illustrate how it is not a reference card

^+1 for the EK. DO NOT GET the Koolance.

@OP: The reason I recommended the GPU only block(MCW60) is due to the fact you can keep using it with your next card with a simple bracket change. Swiftech is good at keeping up with the brackets for new cards. You WILL NOT be able to use the full cover block with any other card (ie can't use a GT2xx on a ATI 4870).

edit: Yeah, OP you seem to have a non ref card, so the GPU only block is your best bet.

Thanks man, I'm not too concerned about upgrading to a new card (this is for a customer, who will not be upgrading, which is why i was hoping for the fullcover) but i think i will go with the mcw60-r.
Also i think it will be fine to use that and 16 of the copper ram sinks to cover the areas that were touching thermal pads. The only other thing that i was concerning myself with is the mosfets towards the rear of the card. I will remount the sink that was over those, I was just a little concerned as to whether or not that would receive proper cooling since the fan of the stock sink is right above it.

as far as the EK cooler I checked that out before and it is close to fitting but the chip at the front of the card (believe its the sli bridge controller) is out of place

Let me mention this. Selling WC to a customer really opens tons of issues if you supply ANY warrenty work. 90 days is fine. After that you might open yourself to long term issues with the quality of the main Koolance unit. It's weak. Even tho it might cool the GPU with lower noise, it's still prone to early failure.

Myself, unless a huge infusion of $$ to build a custom WC rig and able to protect your customers investment, I'd stay away from any WC rig.

Sell air if your a custom builder. There are awesome air cooled solutions.

I run a WC rig, been at it long time.
http://www.ocforums.com/showthread.php?t=604016 I do have a clue about water cooling.

usually do sell air cooled but, had a request for water. When someone wants overclocking I am inclined to use either http://www.thermaltakeusa.com/Product.aspx?C=1148&ID=18... or http://www.zalman.com/ENG/product/Product_Read.asp?idx=..., but the customer wanted water cooling specifically. There is more $$ added on for labor but I am pretty confident in my abilities. I still understand what you are saying (as far as additional risk), in the 6 years I've worked at this company I have built or serviced maybe 15 water cooled systems, the thing i remember going wrong (on every system that had one) is every single koolance HDD cooler leaking. BTW your rig looks sweet. I am however very confident in the systems i build and the work that i do, what i have gained from starting this thread is mainly the more hardcore water coolers tend to shy away from koolance and i will keep that in mind for my next build.

Aftermarket single source parts have more cooling ability and much longer MTBF, plus less noise, and actually cheaper long term usage.

Anyway, thanks for the reply.

Still, any WC rig needs a 6m redo, and a major redo at a year, unless you want 'issues'. Thats my biggest concern with a custom, warrenteed made to order solution.

WC is a hobby, unless your rich, meaning your company too.

also i don't want to sound like i am saying 15 systems is alot in the way of water cooling. Also i agree as far as the warranty, WC adds a big risk.
Thank you again for all of the input I'll let you guys know how it goes after the install. One last added note, Intel is not my first choice as far as mobo's for MY systems but if i can find an Intel board that fits the need, I will take it. Being a partner entitles you to next day over night shipping of an rma.... ship the defective part back in 30 days.... just a side note

+1 to Shadow and the recommendation of the MCW60's. I run 2 of them on my GTX260's and have some decent $10 ramsinks on the memory. Look into Arctic Adhesive if you don't want those RAMsinks to fall off...but note that the stuff is next to permanent.

@OP: If you are building this for a customer, that completely changes the game. Like Conumdrum said they will need to know how to refill the loop,drain,clean,etc.

I would ONLY sell them the WCing set up ONLY if they understand the risks and maintainance need so they won't complain if they mess up (ie leak after cleaning up). Make them sign a waiver or some thing like that. I have built custom WCed rigs ONLY for people who under stand it but don't have time to leaktest, OC,etc. I'm assuming you know what you are doing, but for a small system builder like you and me quality/trust is everything. So far during summer, I have done 15 C2D/Phenom II builds and 5 i7 builds of which 3 were WCed i7s. Built one 2P Nehalem system also.

Also like said above NO KOOLANCE stuff. They are expensive and unreliable, sure thy look cool but that doesn't change any thing.

As far as motherboards goes, Intel branded boards are VERY reliable, but they lack many OCing options found on Gigabyte/ASUS boards.

^Right, Intel boards are typically very good...but you need to look to other brands for more bells and whistles.

I would never build a WC loop for a customer unless they were friends that I was close with...no one I would sell and never see again. I wouldn't want my name/reputation attached to something that fails because the END USER refuses to perform routine maintenance.
