I have a new computer with GeCube HD 4850 GPU.
I am without OC.
Today I saw my temps in load (while fan was on auto speed) the max I saw was: 102C!!!
In Idle they were 65-70C.
So I decided to make profiles for the fan.
Made 50%,60%,70%,80%,90%100% profiles.
While not playing I am just on 50% which give me temp of about 55C and while playing I am on 50-70%, the max I saw was about 70C in load.
I taught I might buy a cooler for my VGA..
Was thinking about:
Thermaltake DuOrb, which I really like and its not very expensive. price is about 50$ for me.
Or Zalman VF1000 which I less prefer, cause of the look and performance. price is about 65$ for me.
Or buy Thermalright HR-03 GT which I like very very much. price is about 57$ NOT INCLUDING FAN.
Do I need a cooler?
If I do, which 1 should I take?
Making Overdrive profiles is the best thing you can do right now short of buying a cooler. Good case airflow also helps tons. I'm at 45% right now for fan speed and i get around 46-47 idle (with minor clocking) and about low 60's on load, so we're in a similar boat with your new fan speeds I'd say.
Judging from the Overdrive temperature gauge in Catalyst, it doesn't seem like 60's is dangerous at all, and more of a "yellow zone" compared to orange or even red.
Only if you plan to overclock would I get a cooler. Otherwise, the fan speed trick has done the job for most 4850 owners at this time. Just don't let it get to 102C again
I think it reached the 102C cause my driver is bugged.
I need to reinstall it and clean it..
Anyway I am not sure it was 55C idle with fan control I should check it.
And my air flow is ok, I have NZXT Tempest and my cables are preatty ok.
You dont think I need a cooler?
Take a look at the Aerocool s1. I have one on each of my 3870's and they run about 20-25c cooler than with the stock heatsink, and that's running the Aerocool's passively. You can run up to 2x120mm fans on them.
i dont know, still say get the Thermaltakehttp://en.wikipedia.org/wiki/Thermaltake CL-G0102 VGA Cooler if for nothing else to reduce that noisy stock fan. for temp it works great on my 4850. while running crysis temps stay in 40's. idle in the 30's.
