Ultimate Cooling Weapon for ATI Radeon HD4870X2

Especially designed for the ATI Radeon HD4870X2, the Accelero XTREME 4870X2 follows the sophisticated design of the Accelero XTREME series, offering the best cooling solution for this high-end graphics card.


  1. Extreme cooling performance up to 320 Watts
  2. Three ultra quiet 92mm PWM fans with low noise
  3. Efficient heat dissipation via eight heatpipes
  4. Patented fan holder eliminates buzzing sounds
  5. RAM and voltage regulator cooling
  6. Pre-applied MX-2 thermal paste
  7. ATI Crossfire compatible

Extreme Cooling Performance

Outstanding cooling comes from outstanding components. The Accelero XTREME 4870X2 is equipped with three 92mm PWM fans running from 1,000 to 2,000 RPM, generating 81 CFM airflow which allows the fans to remove the heat from the two GPUs efficiently. The eight-heatpipe design also improves heat dissipation and achieves a massive 320 Watts cooling capacity. The result is significant the GPU temperature could be up to 50C lower than with the stock cooler. This enhances not only the overclocking potential, but also extends the service life of the valuable graphics card.

Quiet cooling guaranteed

By using low noise fans and a patented fan holder, the three 92mm PWM fans are incredibly quiet. Thanks to the PWM function, the fans run at optimal speed while offering sufficient cooling at the lowest noise level. Even running at full speed (2,000 RPM) the Accelero XTREME 4870X2 operates in near silence, generating only 0.5 Sone of sound that creates a much quieter gaming environment beyond anyone's imagination.

PLEASE NOTE: For best possible results, it is recommended to use Riva Tuner with this cooler.

Customer Reviews

this cooler is well worth it money, saved my gfx cards life


Stock cooler temps: full load, fan at 85%, dam noisy heap of crap:
Cores 95-105c
MEMIO a staggering 125c, that's the main reason I need the cooler
VDDC 115c

Arctic Cooling Accelero Xtreme: full load, fan at 65%, nice and quiet:
Cores 35c-40c
VDDC 55c

It was fairly easy to install; hardest bit I found was the sticky pads, getting the backs off them. Do wish this cooler had come out sooner. Got a 4870x2 1st week it came out and a month later the temps started gettin outa control. I was afraid to use it, thinking it would burn out. Been using a 4850 ever since, so nice to have my baby back. Overall great cooler it's a must buy.

Unbelievable product


I really can't stress enough what an excellent product this is. Just received and installed mine today. Took a bit longer than expected to install, but was simple enough if you take care.

On Auto fan speed (No manual adjustments via rivatuner/CCC):- Previous GPU temps were 60-65 degrees idle, and 85-95 degrees when under heavy load. New GPU temps are 35 degrees idle and 45-50 degrees under load. VRM temps have seen a 20 degree drop also.

That is one incredible improvement, and it is whisper quiet too. Many thanks to Quiet PC for such an amazing bang per buck product!

Supremely Effective at Eradicating HEAT & NOISE Effortlessly


I've made a screenshot of my Catalyst Control Center Overdrive window:

The Computer had been on for several hours, I have never overclocked the GPU's. I have always kept the fan speed at the lowest (20%), the fans cannot be heard.

At full load, playing games, such as Crysis or Far Cry 2 on Maximum Settings, the temperature never goes above 43c, as I have both sides of my case open and my room is cool most of the time anyway. It is the best investment I've made for a cooling solution, since buying the Thermalright Ultra-120 CPU Heatsink.

The performance is astonishing, if you have read all the reviews on this GPU cooler, you know how great it is, all I'm doing it reiterating that fact and the fact that I've typed this "review" goes to show that it is worth every penny, I normally never go and post reviews, this is probably the ONLY exception.

The Accelero Xtreme 4870X2 is like the Mini John Cooper Works of GPU Cooling!

Fantastic cooler with a couple of niggles


Brilliant service as ever from Quiet PC.

Installation took a bit of time, and make sure you use the longer M2 screws to secure the X brackets back on, since the thermal pads increase the distance they need to thread through. Also for some reason Arctic Cooling have only included two adapters for the PCI-E power, and they are both terminating in 6 pins... even though one is an 8-pin to 6-pin adapter. I don't believe this can get the extra power through that the standard 8-pin plug will achieve. I got around this by simply plugging my 8-pin plug straight into the socket... but this is a very tight fit with the cooler installed.

Once installed in my HTPC I was amazed at how quiet this is. It's totally silent when in Auto fan mode, but I set the fans to 100% via CCC and it's as close to silent as possible.

GPU/Mem/Shader temps are amazing. Never going above 55 degrees at full load. However the VDDC Slave temps were all higher than stock cooling, going up to around 100 degrees at l



Great service from QPC and an amazing product. It's a shame we had to wait so long for this to be released but it was worth the wait! I had maximum temps of 109 C and now they hardly get over 55!! And it is so much quieter than the stock cooler.

Don't be afraid, installation is dead easy, just take your time and you will have it done before you know it. Also: it came with the longer screws so no need to get them sent from Arctic. Use these instead where it says to use old screws. The sauna that was my pc room is now a pleasant place to work and game, worth 11 stars just for that.

Best Solution Ever!


What a fantastic cooler this is.

Installed it the moment I got it and never looked back.

40 degrees idle,

50 degrees 100% load.

This is with the fan speed set to 50% and it doesn't make anywhere near as much noise as what the stock cooler does.

Great job on the delivery as well. Just a shame it took so long to come in stock.

love it, love it, love it!


Got this yesterday and it's so good it's untrue!

Install was really easy and painless. It keeps everything so cool and is really, really quiet. With the fans set to 70% in CCC (this is what Arctic say to use to keep the rest of the card cool) you can't hear it over the case fans! Also the cores don't go much over 50c after an hour of COD4!

I have noticed a slight increase in case temps 2/3c but it's easy worth it for the quiet gaming. This was my first order from quiet pc and sure won't be my last. Came at 9.30 the day after they got it in. (I ordered it on pre-order ages ago).

10* for quiet pc service, thanks guys!
