4850's Stock Temps and DuOrb Temps (With Pics) - Page 3

At least 1 manufacturer doesn't think we need them.

I kind of agree with them (assuming you have a good cooler on the card). With the duorb, my core idles at 38C and loads ~50C. Who knows how hot the mosfets were?

But I do know that with the stock cooler, the mosfets were hovering around 90C.
All of the PULSE chips (does the 4850 have these?) and VRMs/MOSFETs need proper cooling. These are the hottest components on the card. They have tolerances for up to 100C+ sometimes, but they can cause instability if you're trying to overvolt.
If you're using water cooling I recommend using copper RAMsinks on them (or Al if you're strapped for cash) and at least 1 120mm blowing across them (best way to orient the fan is the airflow running parallel to the PCB)

I've taken temp measurements with my infrared thermometer in my PULSE chip and VRM area and it was HOT! I'm talking 55-70C hot.....even the PCB was extremely hot to the touch.

Here's an example of my 2900XT cooling setup. This allowed 24/7 gaming stability with 935 on the core (up from 743) and overvoltage from 1.15v-1.35V

great temp drops!

anybody tried this on a 4870? Or is the cooler too weak?

I'll be testing tomorrow with stock air cooling and TIM, then testing with my water blocks and IC diamond.
Results should be brutal.....
Actually, the stock coolers aren't that bad and are pretty general among pretty much all manufacturers. It's not cheap at all. It's got a nice cooper base and I don't know if it's solid copper, ask the guy who sawed his in half, he'll know for sure. But it does a good job once you crank up the fan speed and a decent ambient temperature in the area where your desktop will be located.

While it's loading, can you press your finger on the volate regulator area (the area right underneath the mosfets) for 3 seconds?
I'm not too keen on keeping my finger on anything that hot but let me say that it was pretty hot. Now I can leave my finger on the RAM sink and not notice it being too hot on top so it is having an effect on the cooling. I do want to say that putting thermal tape on the ram sinks is the suck. **** it took me like 2 hours to get them all done again once I took them off of my 8800GT SSC.

Also, keep in mind that my OC is at 700/1100.

Dunno but I believe the 4870 has the same holes as the 4850 and so it would work just fine. The DuOrb is good enough to cool an 8800GTX and 8800Ultra so I'm sure it can cool the 4870 without a problem. Now, if you want something a bit better. This company debuted something at Computex that looks like the DuOrb but is supposed to cool better but I can't find anything about it except for it's debut so who knows until we see some real tests. I will always recommend the DuOrb because it's practical. If you want some extreme cooling, go with the Thermalright HR-03GT or whatever is their new top of the line series.

Copper or not, the fact that people are getting these kind of temps, then switching to aftermarket cooling and dropping by a drastic amount indicates a poor/cheap cooling solution. This is all fine by me considering that I'm replacing it anyhow.

lol it's not cheap when your fan speed is set to 10 or 20% by default. That's the main cause of such a horrid temp. There's quite a few guys that once they get their stock fan over 50%, their temps drop drastically. But that's how it goes with all coolers.

That would be me. It's copper all the way through.

binormalkilla, it's really not a bad cooler for a single slot piece cooling 120w of heat. It does have fan problems as well.

The HR-03GT fits wonderfully and looks like it was built for this card.

The X18/19/38/48 series all share the same mounting holes. The HD2900 series has a huge die that is rotated 45 degrees and requires a special shimmed or trimmed heatsink to work.

Well that makes sense, I had no idea that it had such fan issues. Well that explains the massive temp delta. I'm glad to get these cards because now I can put my monitor on the UPS (my rig was maxing out a 1300VA UPS ) and not have to worry about electrical events raping my $1200 monitor.

True. The 2900 required a mounting plate on my MCW60s, so I'll see if it's required with the 4850s or not.....I'm thinking no, but we'll see.

If your waterblock fits an 3870 or 3850, it will fit the 4850 no problem.

I knew it would fit because I've seen others at XtremeSystems forums, but I don't know if it requires the 2900XT adapter or not.

From what I can tell, if it can fit on a 3870 without an adapter, it will fit on the 4850 and 4870 with no adapter.

Wow you paid $1200 for that. Nice monitor . You should have got yours during BB's HDTV Special. I got a 46" 1080p Samsung LCD TV for $290 with tax and all. I got the 2nd from the top of the line with the 25,000:1 Contrast Ratio and I love it, except for the remote but a Logitech Harmony fixed that problem. I use mine as my tv and my monitor for my old Athlon XP machine as I still use it to save all my music/movies/itunes/zune/ruckus/and whatever else I had on it.
