[Solved] Cooling mod problems for the HD 4850

Alright, I could use some Pro Help here so if you are great with cooling, keep reading

I've added an aftermarket cooler to my card, reducing the temperature at stock clocks from 90c+ on load to 70c+. Now after some heavy overclocking, I seem to have the same problem again. I'm back to 90c+ temperatures. I'm really looking into some solutions that don't include water cooling or some really heavy mods. Airflow inside the case is great although a pci blower just might help a tiny bit.

This is the aftermarket cooling I bought

Now the heatsinks that came with it are rubbish, so i'm looking to purchase some forged copper heatsinks from either enzotech or swiftech. My Problem is here. Due to the nature of the cooler, some of the forged heatsinks would have to be bent in order to fit. How would I go about doing this without damaging the heatsink. Here is an example.

Secondly, is there any place that i can place additional heatsinks to the back of the card without shorting it out? I have heard that some more heatsinks in the right spots will cool even further.

Similar idea, at least conceptually, with the Thermalright HR-11

Thanks for the input

Thats not a great GPU cooler in tests. Not enough surface area on the fins.

Yep, thats how you bend them!

You might have poor case circulation too, have you checked temps with the side of the case off and a house fan blowing into it?

Hmm, I wouldn't of bought the cooler without having some solid reviews.

Anyway, best of luck in the extra heatsinks, get mo' air on that card, increase case airflow and add a fan somehow to blow across it. Not much more you can do.

You could always drop the overclocks ya know?

Don't talk about things that you have no knowledge about. The card was well over 150 when i bought it. I also bought it when those cards came out, most had just about the same cooler. How nice to have a good cooler on the same card, several months later, even a year. Imagine that. I have 4 friends with "factory overclocks" and they have even done some tweaking themselves, and i've beaten them all in comparable or even arguably better cards.

All I was asking was about the heatsinks, but since only Conumdrum provided some kind of useable feedback, I guess Toms forums doesn't know much about modding. I'll go elsewhere
Thanks anyway
