Like for like replacement for my GTX480?

Can't work out if tommybhoy is trolling or genuinely never went to science lessons at school.

I was reading in the paper today that we are on track for the warmest November in 350 years.

If you can sweat it out for a few more weeks nature may solve your problem for now then in the spring you can look for a new card when the shiny next gen are out.
 
Lol this is a funny thread. My room gets hot in the summer but saves me putting the heating on in the winter :) I have 2 gaming pc's in a small room but find sitting in my pee wee Y fronts helps :D

It was a genuine question. You accept that in both instances the same amount of energy is dumped into the room as heat but insist that the heatsink with a lower surface temperature will warm the room less.

All that is happening is the more efficient heatsink is warming a larger volume of air to a lower temperature. The less effecicient a smaller volume to a higher temperature. The energy contained in that air is the same in both instances.

As soon as these warm streams of air hit surrounding cooler air they mix and move towards equilibrium.

Increased airflow may give the impression of less heat being generated in the immediate vicinity especialy if the case is in an enclosed space but on a room wide scale makes no difference.

I see you put a lot of input into the thread mate by pointing out the obvious that winters coming.

While your advice may have been well intentioned it would have wasted £45 of the Vegeta's money.

Wish I could do the same. 2 of my housemates insist on having the heating on and I can't stop my radiator actually being filled with hot water

You should still be able to.

What do the lockshields on each end of your radiator look like? Anything like the pic below?

Do either of them have plastic caps on? It is quite often the case they get lost over time.
 
Anyway back to the topic of the GTX 480 - would the OP be looking to sell his old card? If so what make it is?

(i agree though that regardless of how its cooled the room will heat up the same - energy cannot be created or destroyed)
 
With the explanation above, would that not render all coolers the same?

Wouldn't high end cooling ultimately have the same cooling effect as a simple stock intel sink, as the ambient air would end up being of equal temperatures?

'As an aside, using the stock cooler I recorded a system load wattage of around 400 watts. This dropped to 384 watts when using the Shaman. Part of this would be due to the speed of the stock fan spinning so fast but I also believe it has to do with the GPU operating at nearly 30C lower temperature. A nice little side bonus as we are likely seeing less power leakage from the GPU at lower temperatures.'

I'l stick to using custom cooling, as imo it's a much more pleasant cooler and quieter experience, than sitting in a warmer, noisier environment with stock cooling.

Maybe it works different up here in chilly Scotland!
:rolleyes:
 
Your GPU may be getting to 90C but the heatsink will never except maybe at the immediate point of contact or interface.

As has been said

Electrical energy in = heat energy out

nothing to do with the size, shape or number of fans.

Two separate issues:
  1. How efficient the cooler is at moving heat from the card into the environment
  2. What effect that energy has on the surrounding room

The Ambient air would eventually stabilise at the same level irrespective of the cooler used (assuming the card didn't melt and stop working ;)) - However, but using a more efficient cooler, you can move the heat into the environment faster, allowing the card to stabilize at a lower temperature.

'As an aside, using the stock cooler I recorded a system load wattage of around 400 watts. This dropped to 384 watts when using the Shaman.

I'm happy to be corrected - but that is complete drivel!
