Excuse me I have two questions:
A) Does the 4870X2 have the same issues and if so would an EK FC waterblock take care of it?
B) If not the EK what is considered the best FC block out there for the 4870 X2

I went with Danger Den, but I'm sure all of them are far better than air cooling.Quote:

How stable is your 865Mhz core overclock with the MCW60 + ramsink/mosfet sink combination?
I ask because i'm thinking of doing this too.
Is it game stable for long periods of time do you know? And is that on stock voltage? Questions, questions, questions ;)
hello i'm running at 880/1100 ! rock solid !! no problems(i'm using 8.9 )
don't worry about it as long as you increase the voltages or flash to a different bios (i'm very happy with the extreme-pc hd4870 maxx fps bios ):)

Anyone know of any reviews comparisons of 4870 full coverblocks, thinking of getting two and was wondering if anyone stands out or there all pretty much the same
they are all pretty much the same !
I think lots of you guys are using way too small VRM heatsinks.
The regs byproduce ~20W heat so slapping some tiny-winy RAM sinks on them won't be enough. And those Pulse inductors like to be cool too as the quality of the current they pass along depends on the temp of the device. Sure they can take 100ºC+, but...
I'm contemplating on snatching a PowerColor HD4870 PCS+ 1GB as I'm getting seriously bored to my age-old G92GTS. I would slap a MCW60 on it along with some hack-sawed alu sinks (salvaged from a CRT monitor):
Attachment 86218
Photographed on a Radeon X1800 for reference of it's dimensions.
The sink needs just some mounting holes and a little cutting to fit on a HD4870.
WCUK will be getting them in, they do international orders as well, just email them for shipping price on it :DQuote:

We will also have a new variant ready to the end of the next week:

Both copper blocks are connected via a Delrin bridge so the voltage regulators are also watercooled :)
The block will cost 79,90 EUR.
Nice block Shoggy. So water flows through the delrin bridge? Where are the inlet/outlets?
Ive always loved AC styles
They are on the backside like here (not that block!).
And yes, the water flows through the bridge.
Damn those blocks both look really nice, too bad I just moved to an x2 :D
This may be old news but don't these work?

Custom HD4870 Cooling Kit by iandh - Red
I am thinking of WC'ing my 4870 but are still these problems?
yes from what I've seen those iandh kits are great :up:Quote:

Currently we offer two different variants of the HD4870 block:

SO i'm assuming the 2nd one has an analogue PWM?
yep
Rob at WatercoolingUk is the only shop to have the new golden sample 4870 blocks to buy :D

I thought those kits had problems cooling the VRMs unless they had a fan blowing or something... it was brought up before I think.Quote:

Been looking for reviews, none found.
all heatsinks need fans to blow on them.....Quote:

My loop goes: swiftech 18w ddc - swiftech GTZ - mcw-4870 - MCW-NBMAX - black ice360 rad - xspc res - back to pump.
My 4870 (820/1100) temps dont get over 40c after hours of Far Cry 2, and CPU temp isnt over 35c. (E8400@3.8)
I'll crossfire another one this next week and split it into a GPU and CPU/NB loop.
