New Cpu (PhII965BE) in HP OEM help!

Nice to see HP can bugger up an AMD based board's bios just as well as an Intel based one.

With regards to that vcore reading, if that was correct the CPU would have fried itself regardless of what the fan was doing. Not only is the vcore wrong but there are 2 other readings the same. Also if the 12V reading at 8.64V was right, the computer wouldn't even start. Looks like they managed to bugger up most of those readings with their hacked up bios.

As far as not being able to see Cool and Quiet in the bios, probably find that HP in their infinite stupidity have left it enabled (which is the default) and hidden it.

This is a pretty old thread, but I wanted to post an update. Maybe those running this type of hardware will be interested in the results I've achieved, which are kind of amazing.

Here's a screenshot from today after running 3DMark Vantage, the AMD Froblins Demo and Crysis 2. These temps in contrast to what I had been getting are just awesome, and I did it without spending more than $20.

[Ignore the voltages, HP's clever engineers made a complete mess of it]



I've pretty much reduced all the temps by over 30*C. Rather than spending big cash on a HSF and aftermarket cooler for the Gpu, I decided to look into how different fans work, sizes, speeds, etc etc.

What I wound up doing is picking up two fans that are typically used as exhaust fans for a system chassis, and using one on my stock AMD heat sync, for the Cpu, and the second on the Gpu. I also picked up some Arctic Silver 5 and redid them both. These fans both spin pretty quick even at idle and are probably 3-4X quieter than typical fans for this purpose, which tend to be a bit smaller, and spin at much higher rpm.

The CPU setup looks fairly normal, just with a kind of large fan on it, these fans are both standard 80mm DC Brushless. They both idle at exactly 1,500rpm and spin up no higher than 2,200rpm for me, though I'm sure they could hit 3,500 or so, perhaps more.
As for the GPU, it does look kind of ghetto hehe.. I removed the cover/shroud/fan entirely, all that's left is the PCB and heat sync. I then attached the second 80mm chassis fan(wasn't easy but I figured out a way to do it, being kind of creative and a bit lucky that the shape of the heat sync fit the fan perfectly) to the heat sync, and ran some demanding benchmarks. The CPU fan is hooked up properly to the board just like the standard one would, however the GPU fan has a different connector, and so I tried plugging via an adapter into a 4-pin molex to see how the fan would behave with zero fan control at all. The fan spins at it's minimum RPM, and as the GPU heats up, it speeds up all on its own. Just for kicks I spliced into the GPU's power connector, and the only real difference is the driver controls the speed naturally, however the minimum RPM was too high and noisy for this size fan, so I actually decided to leave the fan powered directly off of a 4-pin molex adapter, and it runs perfectly. I took a lot of precaution obviously and ran a lot of tests.

In the end, this is how I have the HP setup, and it runs ice cold, both idle and under load. It runs cooler than my Gamer rig in every possible way, and the gamer rig has very good cooling hardware. It's also much quieter than my Gamer rig, even tho I'm honestly using fanstastic hardware on it, including a good push/pull setup and an aftermarket cooler on both the Cpu and Gpu. Even with the gamer rig at stock clocks, the HP runs cooler and quieter.

So anyway, I wanted to post this because the cooling performance is kind of amazing considering I spent only $20, and these are the best temps I've seen since running an Athlon Cpu back in the late 90's!

So, am I the only one around here to try doing this? Or am I just lucky, as far as the Gpu go's, that the 4890 just so happens to have a heat sync that seems specifically designed to take one of these fans? I'm curious if anyone else has done this, either by choice, or because they had a fan failure and maybe had to. I should also mention, because of the shape of the 4890's heat sync, the fan is actually cooling the memory as well. The air that gets spun off the side of the blades pushes its way down the sync and across the PCB right over the memory, I even had a look at the memory temps in GPUZ and they're 12.5*C cooler than the best temps I'd even seen using the stock fan/shroud! Because the Gpu runs so cold, there's no negative to not using the cover to push all this air out of the case, it's just never hot enough to really make a difference. Although lately I don't even keep the side panel on anymore, because of the way it's setup and where the tower sits, any noise I would normally hear, I can't, again just a bit of luck in how it's all setup. Really cool stuff.

Notes: Redoing the thermal compound on both the Cpu and Gpu helped quite a bit, I was very surprised. I did this 'after' I finished this entire setup, because I wanted to see just how much a difference it would make. The Cpu came down about 5*c, and the Gpu slightly over 10*c, both idle and load, it was about the same. I should mention the compound on the Cpu was still very much fresh it's not very old, this should say something about how much compound AMD likes to use, which after doing this, I can say without a doubt, is NOT enough. The Gpu looked about right, they were very liberal with it, and the only reason I saw such an improvement was because it was old and just crusty and a bit uneven.

Additionally the Cpu temps above are about the max I get no matter how I stress test it, the Gpu temps are usually slightly less, however the AMD Froblins demo pushes the Gpu harder than anything else I've run (I haven't run furmark which I'm sure would push it just as hard) because it uses lots of tessellation and AI, all on the Gpu.
