Many questions for 5870 E6 - VR3, VR4, or VR5 with fan? Accelero Xtreme?

post #1 of 3
Thread Starter 
Hello everyone. My 5870 Eyefinity 6 runs a little hot (and quite loud) and I'd like to cool and silence it. I have been looking into the Accelero Xtreme 5870 as it does a great job at cooling and has excellent reviews, however it is LONG and I'm not sure if it will still fit in my Antec 300. I don't have any drives in the bays behind the card, so I'm only worried about whether the cooler will be skinny enough to fit between the two sides of the drive bay. I also know that the VRMs on this card ALWAYS run hot and was looking into the VRM R3, R4, or R5 and they all look to be the same, just with different orientations. Do I need a fan or will the airflow in my case suffice? Recommendations for the fan?

tl;dr version:

Will my 5870 still fit in my Antec 300 with the Accelero Xtreme 5870 cooler?
Do I need a fan on the R4 if I get one? Any fans that are dead silent and will keep the VRM's cool?

Can't answer about the accelero xtreme, but as for the thermalright vrm-r#, I run mine passive. Too be honest, I don't remember exactly the temps I'm getting, but I don't believe they ever break low 70's under load, whereas stock had them in the upper 80's and beyond. I imagine that putting a fan on the vrm will help a bit, just don't expect it to help a ton. If you have good case air flow then I'm sure you'll be fine as well running passive.

If you don't want a hassle, you could install 2-3 fans directed, or better yet vented directly to your graphics card. The blower fans are not good with airflow, but their pressure can easily equal 2-3 normal fans. So they can work in conjunction, according to my practical math.
I cannot recommend unless you specify the dimensions compatible with that vrm piece, but since you have an Eyefinity 6 card, you could probably buy tier 1 equipment like Scythe Gentle Typhoon. That is the best in sound profile bar none imo.
