Arctic Cooler Accelero Twin Turbo Pro freshly installed on XFX 5870

[Spare-Flair]

Last night I spent an hour installing the Arctic Cooler Accelero Twin Turbo on my XFX 5870. There was a sticker on the packing saying "new compatibility 5870!" so I don't know if this version is different from the others I've seen before. I did notice there seemed to be two heatsinks that I didn't see in other pictures before and they had adhesive stickers that were different from the rest indicating they were new additions to the package.These ones are like the old VRM heatsinks except they have an L-shaped step and larger fins to clear the resistors that sit behind the VRMs on the 5870. I added some arctic silver between some of the heatsinks that touch each other so they could share heat but that was probably pretty useless but I did it ayway.

Here's how it looks after I installed every heatsink that came in the package. Clearance was fine, it all it fits with the main cooling unit installed. The only thing that disturbs me is how heavy the cards is now with how long the PCB is, when installed in a system that has an upside down motherboard, it actually causes the entire card to sag.




Card is sagging to the left, looks like it's slightly angled. Works fine though.

That sag is meaningless. What's important are the temps. How are your temps under load? Could you put up a comparison from where you were before to now? Also, what fan speed under load and what is the noise level?

Temps, noise?

[Terence52]

wow.
looks great
temps pls
actually the card sagging shouldnt be much of an issue.

My case is actually pretty hot because of the reverse airflow setup, there's a deadspot near the card and I need to get the new Lian Li lid with a blowhole.

Idle is dead silent, the fan hardly spins up from the minimum setting. But because of the current airflow issue I need to fix with ambient air pretty warm, the idle temps aren't too much different from stock.

Temps are around 15-20° C lower on full gaming load but it's much more silent than the reference even on max. I can't barely hear anything in my system anymore except for my PSU.

I have read forum posts from people with good airflow setups that have reported up to 30° C cooler from reference when gaming.

So, these are core temps, correct? What about VRM temps? These bother me much more.

Unfortunately, I have no way of measuring stock VRM and new VRM temperatures.

idle ? full load ? with furmark plz ?

Ahh, thanks, I didn't know that GPU-Z monitored VRMs.

Unfortunately, I don't know what the stock temps are and as I stated before, there is a deadspot around the card I need to install a blowhole for so the temps may improve.

I don't have furmark right now but I'm playing Metro 2033 for about 2 hours and the VRM temps are around 70° C each. What are the VRM temps with reference cooling?
