What coolers to go on a 4870 1gb

I tried Everest to see if it would tell me what my VRMs temps are,but it didnt.
Could you tell me what software to use to see the VRMs Temps?
GPU-Z doesnt tell me,only the GPU TEMPS.

GPU-Z for me... it's the three VDDC Slave temps at the bottom of the page that you're looking for. On mine after some testing using Crysis final stage to load card for an hour or so the VDDC Slave#2 was highest so I tend to use that temp as being the 'worst case' for VRM monitoring.

If you look Above your post,you will see that i cant get the VDDC Slave temps in GPU-Z.They are not on the bottom of the page.
Do you have the 4870 1gb v/c?

I saw that you couldn't... you asked what I was using - well GPU-Z is it.

If you look at my sig then you'll see that I am using a Powercolor 4870 1Gb... also if you look at my earlier post regarding the Accelero Twin Turbo... "Got one on my 4870 and it's very good."

So let's not get pedantic over who's actually bothering to read the posts eh? ;)

We are after all just trying to share the experiences we have all gained in the hope of helping others.:)

Im not getting pedantic,im just wondering how your GPU-Z is showing the 3 VRMs at the bottom of the page,and mine isnt.
Why it showed the VRMs in the 512mb v/c,and not in the 1gb v/c when i installed it.?

I have read that some of the Sapphire non-reference design 1Gb 4870's do not have VRM temp monitoring, so poss that is the cause?

This comment "Cons: This particular Sapphire uses 3+1 phase analog VRMs. Sapphire used 3+2 phase digital VRMs in their other 4870 designs. There is no VRM temperature monitoring on this design. GPUz, nor any other monitor software will not show you vrm temps. Kind of a bummer if you want to overclock and keep tabs on that sort of thing." was posted as a customer review on page 3 (near bottom) of this link.

Hope this answers your question. :)
 
I found this from another forum:

Went to the website you gave me,it looks like im out of luck with this Sapphire v/c,so you probably are right about the VRMs.
Guess i will have to keep an eye on the GPU Temps,until i change the cooler.
Didnt know its a non-reference design.
thanks.

No worries m8, sorry it ended out that way for you. As long as you get good airflow over those VRM sinks you should be fine with any of the after market coolers.:)

Do you think if i put a 120mm fan behind the back of the card,would it cool the VRMs down.
If that works,i wouldnt have to get a cooler,and also not jepodise the card if it goes wrong,for an RMA.?

TBH without knowing your exact card it's kinda hard to say. But having looked at the Sapphire 1Gb 4870 here then it looks to have openings in the cover (which I can't really understand!) - and according to one of the comments it vents some hot air inside the case!! If that's so then a fan directing cold air onto it should help, but rather than a fan inside the case recirculating warmed air and working against the airflow of the onboard cooling I would stick with a case side fan to feed cool air to the graphics cooler if your case has that facility. With mine I used to run my side fan as an exhaust as I was trying for negative case pressure, but found that the VRM's were much cooler running it as an inlet. I believe the VRM's are rated to 127 degrees...:eek:

I would expect Sapphire's cooler to do a good enough job on it's own, but if you are aiming to OC the card then some additional cooling as above couldn't hurt. So you are prob best to stick to the stock cooler to avoid duff warranty etc as you've said. Whatever you decide good luck m8 and happy gaming :)
