Chipset Power Consumption

cadaveca 23rd May, 2006 05:42 PM

I highly agree with that posting...using the same cooler on the NF4 and the RD480 as well as the RD580, actual temps get progressively lower, in the order listed.

nVidia made the move to a open-die package a while ago, and the addition of features since then has naturally increased package size and power consumption, while ATI made the same package move just recently with the RX5XX platform. ATI's chipset seems slightly smaller in size too, lending more weight to this argument.

Are there options available for avoiding the eventual melt down?

I don't see it as being a "meltdown", per se, but it could, in turn, affect overall clockspeeds of these chips. To the average user, this is no big deal, but it might dissappoint a few hundred thousand overclockers that buy cheap cpu's, and rely on the motherboard to extract the performance they desire.

The newest chipsets, from any company, still run relatively cooling tends to lay in the 40-70c range, dpendant on chipset, while passive cooling tends to get much hotter. Be this as it may, these chips are still well within thier thermal envelopes.

However, add a top-end videocard that has it's power regulation circuitry right above one of these chipsets, and those temps can rise cooling barely does the job, and passively cooled chipsets are no longer stable(ones with heatpipes are excluded from this mix, and tend to fare as well as an actively cooled chipset).

So, with this in mind, and thinking of bigger chipsets, and the increasing difficulty in cooling a larger chipset, it can be a bit forboding for those that tend to think this way.

I think that it really will be overcome, look at the old P3. They used 2volts at stock never mind w/OC. It will be fixed, ATI is doing better now buit that can easily change.
About the VID card things my 7800GTX blocks my NF4 chipset, it runs hot but never goes over 40-50C the fan on it's amazing. One thing though is since I watercooloed my GTX without the GPU fan it runs about 40-60C

Thanks for the info! ":O}

It appears that water cooling will truly benifit these chipsets. This would atleast keep the heat of your card...

thats what it would seem, but when you don't have the huge CPU fan o r even the small GPU fan you chipset gets hotter, especialy if the end of your GPU is over your chipset.
