ATI x1900gt VRM thingies

[gurusan]

So I hear these can get pretty hot when overclocking...and mine idle in the mid 50s and go to 68c sometimes during gaming...however I touch them with my finger and they don't seem that hot?

They are the little strip of chips next to the funky heatsink thing on ati cards right? The things there on the left that say Pulse?

The reason I ask is that I will be putting the card under water and pushing it until I can afford an 8800GT....and I have a spare set of BGA heatsinks that I can put on them...just wondering if it's worth it or not?

you going to H2o for noise of performance ? reason I ask is if it's the latter just pick up an old fan and hook it up directed at vrms. try it without adding heatsinks

Any cooling you can give to the VRM's on these boards is beneficial Some peeps make up heatsinks for them etc.

im going for performance....although the fan on this IS incredibly loud. I've always been nvidia and WOW ati is freakin loud as ****

Anyway thanks for the input...I might slap them on as they were only 3 quid

the VRM's are actually UNDER the heatsink, to the left, the pulse marked components are coils or capacitors, i forget which but they dont need cooling. to the right are SMC's or SMR's (surface mount resistors/capacitors) again, dont need cooling.

if your going WC, koolance make a waterblock for these. and another for the gpu/rams. costs a prety penny however- looks nice tho

oh so there's already a heatsink on there! hmmm

**update**

moved my HD cage with a 120mm fan in it up 1 slot and my VRM temps don't ever go over 55-58c now! Apparently there was a dead spot in my case or something

yes as mentioned above the vrm's are under that red heatsink. you can get a bigger heatsink for them too, the heatsink comes with the accelero s1, and im sure there are many buyers of this cooler who are not using the vrm heatsink since they may be using the cooler on a non x1900 card, so plenty to buy on the cheapo. iv done a thread on this as well with pics too of the larger vrm heatsink.

Well yeah now I got it sorted since I moved my HD cage up. I had the card overclocked to 750/865 and the VRMs were hitting 85c. but like I said now they only go to around 55-58c which is quite acceptable.

if you can get a larger vrm heatsink for your card for like 3 quid or so then you may as well get it just for added cooling.
