Windows 7: New Cpu (PhII965BE) in HP OEM help!

New Cpu (PhII965BE) in HP >>UPDATE<<


I just put a new Cpu in my HP rig, and it's running very hot. I'll try to be brief. (Specs in sig)

HP HPE-112y with 850W Psu & Radeon 4890.

I just replaced the factory Ph II 925 2.8 with a Ph II 965BE 3.4. Right away the mainboard hit 72*C, so I installed my Antec 120mm 2,000rpm fan (which I intended to do once I finished and knew the setup would work) and temps fell to normal, idle about 41*c/105*f. It warms up quite a bit, but no hotter than it used to with the 925, so I'm sure this is fine.

Here's the thing; The Cpu is idling at 45*C @ 800mhz (It's warm in the room, but not bad, 75*F tops...not warm really heh..) it's hitting 66*C, but in only a 5 minute stress test, I fear testing any longer, AMD says 62*C max, I'm sure it can go higher, but I don't want to risk anything, for now.
How hot is too hot? Also, important, the thermal paste that came with it, which was pre-dabbed onto the bottom of the heat sync, take time to set?

I'm not used to heat like this, my other rig is just so very different, can't compare them, also, this is the very first time I've ever put an enthusiast chip on a OEM board. So yeah, Cpu is too hot(Using the HSF it came with from AMD) motherboard cooled off incredibly with the new fan.
Oh lastly, my Ram, PC3-10700, 667mhz, was always at 533mhz before, 7-7-7, now it's 667mhz, and 9-9-9, perhaps this is normal. I just don't fool around this much with hardware... uhg.. I can't adjust anything in the bios!

Please help me, and sorry for the length guys, I'm so stressed..

  • Get some good thermal paste
  • Install an extra case fan
  • Disable energy features that automate your current fan
  • Organize your cables

Cables are very neat, using a modular Psu. I have the extra fan in, but I'm curious; I've never tried having a fan blow "in" the case, the reason I'm curious, is the fan just happens to rest directly above the Cpu HSF and NB/chipset, is this worth trying? Because I already have a 92mm exhaust fan, pulling air straight from this area.

I will buy some thermal paste, as for the software controlling the fan, I'll have a look. I've never had an issue leaving it alone, but it really seems to not want to spin up over 3,000rpm, I'm assuming it's capable of 6k or so.

Edit: Also, I just stress tested it, and it gets up to 68*C, and then backs off to around 65*C, and stays there, however the fan certainly isn't running it's highest, I think this may be the software controlling the fan. I'm going to install AMD Overdrive and create a profile.

Should I try reversing the 120mm 2k fan? It's on high, @ 2k.

If that HP case looks anything like this,

best I can say is to get a decent sized case with good airflow. You have to remember you just went from a 95W CPU to a 125W CPU, so there is going to be extra heat. Also if it is that case with a 4890 in there, there is even less airflow getting through.

That is my identical case, imagine the 4890, and a huge Antec 120mm right on top of the HSF and NB heat sync.

For now I don't mind it hitting 68, however idling at 44 or so bothers me.

One other thing, this I'm very curious about but didn't want to load the earlier posts with even more text; My old Cpu, and this new one, both, run at 2.16V, is this normal, it reads this in every program I can think of. Is this the board just being a bit.. different? CPUID HWMonitor, CPUID PC Wizard, AMD Overdrive, etc etc, all report it this way.

I simply never mess with this type of stuff, I understand many things, but not this heat, and certainly why it says 2.16

you could have a front fan blowing in and a back fan blowing out. Similar is the PSU fan blowing out the back. And see if your bios is regulating your fan. My Asus has the software option of controlling the fan. Forget that...

I've narrowed it down, there's simply no doubt in my mind, that my motherboard is keeping the Fan spinning at far too low RPM. There's no option in the BIOS to change this..uhg. I'm gonna try Overdrive, not used to it, can't find the option yet, otherwise SpeedFan I guess.

Judging by the speed my Cpu fan is capable of (Same fan everyone with a stock 955be/965be has) 1200rpm idle and 3k load is simply uncacceptable.

Perhaps the reason I cannot find a fan speed option in Overdrive is because my BIOS doesn't allow me to change it?

(I should have bought a second Asus board...I know )

I have a piece of crap HP desktop in my lab at work, and it does have a speed control. You can enable Cool and Quiet in the BIOS (Still need the drivers), and there is another setting for the chassis fan. The CPU fan is under the CPU Config tab, I think, and the chassis fan is in the hardware monitor.

Have you seen either of these options in your BIOS?

And I would turn that fan around so it blows in, if you haven't done that already.

Edit: My Phenom 965 desk PC at work has the fan running at 3300 RPM with the stock cooler. Average idle is 33 to 35 with a room temp of 22 to 25C if that helps any...

Fan is now blowing in, also I have absolutely no options for Fans in my BIOS. Speedfan and Overdrive won't allow me to adjust. The rpm's are just too low, when it heats up under stress, and the fan begins to speed up, it kills off the heat mighty fast, this will be incredibly frustrating if I can't figure out how to adjust it.

Also I don't even see anything about Cool & Quiet in the BIOS.

Edit: I think I'm gonna have to live with the idle temps, until I get a new board, xmas maybe I'll grab one for myself. I've gone over everything I can imagine; If anyone thinks of anything, I'd be glad to hear it!
Otherwise I'll keep an eye that it doesn't run past 65*C or so, for now, and throw some good thermal paste on it tomorrow. I have a feeling I could lose several degrees doing this, since AMD puts a very thin amount.
