Arctic Accelero “backside cooler”

[britain4]

Been considering a couple of Arctic Accelero Xtreme IVs for my cards - was planning a full custom loop but I may just do that on the CPU or stick with an AIO. Only problem would be if they’re not compatible with a future card I buy as obviously it isn’t worth spending £50 I can’t get back on a 780 ti at this point.

Anyway the older models come with heatsinks to stick directly onto the VRMs and RAM chips directly under the cooler with the fans blowing on them, the newer ones come with a rear mounted cooler that contacts the back of the PCB where the VRMs etc are mounted

Anyone got any experience with these and how are your VRM temps? I’m very sceptical of the ability to be able to cool them effectively through the PCB with nothing directly contacting the front of the chip (although they’d still have the fans blowing on them).

The traces in the PCB can sink heat as well - but I'd be kind of sceptical as well this will do much if the cooling on the other side is sufficient.

Well, there is no cooling on the other side with the Xtreme IV, just bare chips and VRMs. According to Arctic it’s fine but if the heat’s got to go through the back of the chips then the PCB then thermal pads before the heatsink I can’t see it being very efficient.

Ive had Arctic coolers on my gfx cards before and they have been stellar, i would doubt they would release something that doesnt work well. I would have thought a combination of fan air on the ram/vrms plus the massive sink on the back would keep it cool...only one way to find out

Yeah the cooler itself looks really good but I just have serious reservations about that backplate thing. Nothing stopping me from sticking some heatsinks on the front of course but seems to defeat the object a little bit.

I would just go for it but there’s no VRM temp sensors on this card so I’d be finding out the hard way if it wasn’t good enough!

From what ive seen it looks like a great cooler, if you are worried just get some thermal adhesive and some small sinks off ebay to put on the vrms for peace of mind. But seriously i doubt you need to, arctic cooling have always been quality even if they are cheap
