Thermalright Readying Series of VRM Coolers for Radeon HD 4870, HD 4890

Thermalright is readying a couple of VRM area coolers for the AMD reference design ATI Radeon HD 4870 and Radeon HD 4890 graphics accelerators. The Thermalright VRM-R1 and VRM-R2 work in conjunction with the company's T-Rad series GPU coolers, and strive to provide a high level of cooling that allows better overclocking.

The cooler consists of an a heatsink that covers the VRM area of the accelerator. From this heatsink arise two nickel-plated copper heatpipes that convey heat to a small but dense aluminum fin block. This block is big enough to let you latch an 80 mm fan onto it for active cooling. Both VRM-R1 and VRM-R2 are essentially similar in size and shape of the components, except for that the two differ in the positioning of the aluminum fin block. For VRM-R1, the block propagates perpendicular to the plane of the motherboard, while that of the VRM-R2 propagates parallel to the plane. Both coolers weigh 160 g. They are compatible with most Thermalright GPU coolers, namely HR-03 Rev.A, HR-03 GT, HR-03 GT V2, T-Rad2, and T-Rad2 GTX. They will hit stores very soon.

i hope you can rotate them, i'd like my VRM coolers above the card... but not sticking THAT far out (useless for crossfire, etc)

i'll need pics of the second one before i can tell how it'll work in a case.

Looks pretty awesome... Is that a 92mm or an 80mm fan on the fins? I wonder if you can sandwich a fan between 2 of them and use it in a CF setup... :p
EDIT: My bad... just now noticed that it says 80mm... :D Still, this will be an awesome solution for cards that don't have enough cooling. Or even coupled with a GPU cooler.

Don't get me wrong, I love Thermalright products, but to fully equip a single card would cost what, a hundred bucks? Back when a single 8800 GTX was "enough," I used one of their coolers.

I've ran at least two cards since then and choose multi-gpu's with modest oc's and stock coolers over a single aftermarket cooled card. If aftermarket, it's gotta be multi-gpu friendly both in design and cost. Maybe things will be different with a DX 11 flagship, but for now, gotta have two cards..

awesome Idea but does vrms really need a H/S that size?

Yes, even on the stock cooler I saw my previous 4870s VRMs temps hit 120'C.

When I changed to the Accelero S1 and used its VRM heatsink, which had the VRM temps hitting 120'C. I had to mod it to use 2 120mm high flow fans to get temps down to 75'C under load.

VRMs produce an astonishing amount of heat, and start to deteriorate at 120'C.

Lol, pretty sure thats why I had to RMA mine in the end :P

i use accelero S1's and 70mm fans on the VRM's - the VRM's get hotter than my GPU core.

Nice, but too costy for me (and i have only 4850)

Sorry to say but you need some better airflow if thats the case, or to turn the stock fans up when running Furmark as that is about the only thing that will make the cards go that high.

That said, even in my Lian Li that isnt the best airflow with stock air cooled 4870's my temps never went above 105'C on the VRM's and even thats too much.


Water temps are much better than air but this doesnt seem such a bad idea to be honest, if your into some serious clocks on your cards. :toast:

oh, this is perfect. Blow the hot air from the vrms into the cpu heatsink! Awesome! :rolleyes:

With a copper cooler on my gpu and copper heatsinks on my vrms (and whatever those things are next to them) on my 4870 my core reaches 85C , and my vmrs around 100C.

now we just need the 120mm version :laugh: :shadedshu

I can see the mods now for e-peen a minimum of a 140mm fan is required. :roll:

Case temps hardly matter, it's a bad card design from the start. Some of the HD's just get ridiculously hot. My card shuts down from VRMs overheating all the time when overclocked. That was with an HR-03GT cooler on it... The core is just fine, but not the VRMs. I put the stock cooler back on because it did a better job with the VRMs, not much better but still better. I was going to mod my own VRM heat pipe but just didn't have the time... I may check one of these out, will allow me to up my voltage and hit 860 on the core easy.

Why Thermalright doesn't make a single cooler solution that covers the ram, core and vrms all as one piece, like the stock cooler but more efficient. Those little ram sinks don't do anything. They are back pedaling now because they forgot something. So with the HR03 and one of those VRM coolers, I think my PCIexpress slot is going to break off the motherboard.
