Replaced CPU and saw that HP didn't apply any thermal grease? Normal?

I replaced my CPU ( thread here), and noticed that the old cpu T2400 didn't have any Thermal grease on it. Is this normal? Basically, it was clean. Did the commies forget to apply it or is this normal?

The cpu I replaced it with, I applied a small amount of thermal grease to it.

 

was there a thermal pad?

 

probably had the pad, check under the heatsink for a grey or dark colored square.

 

Oh crap. that means i applied thermal grease to the pad. i didn't check to see if it had a pad. crap. to lazy to take it all apart again. should I be worried with the thermal grease and pad going at it at the same time.

 

Overall, not much will happen, the CPU will just be insulated a bit and thus retain more heat. So other than running slightly hotter nothing bad should happen. Harmless, but a newb move on your part.

 

i know, never heard of a thermal pad. Don't they melt into place anyways?

 

No... its just a pad not a magic melting pad...

 

I dont remember HP using thermal pads on CPU's.

My old HP didnt have a thermal pad nor paste. Just straight to the heatsink..

Are you sure you saw/didnt what was on the surface of the heatsink? It should have been shiny like silver.

Some thermal pads have wax on them that melt and fill up the nano-gaps when heated. Not literrally melt as you would imagine though.

 

All I remember looking at was the CPU and it was bone clean. No thermal paste residue or anything. Under the heatsink I do remember seeing a square shape thing, but that could be just the heatsink itself.

 

Check the service and video manual if it uses a pad, paste or nothing. Definitely show up there.

 

There had to have been something. Without some kind of compound/pad, your laptop would have shut off seconds after turning it on.

 

Haha.

But you should get a bit higher temps, but other than that, nothing bad should happen. There basically little greased up pads, they just transfer the heat.

 

On my dv6500t they had this crazy little peice of foil for the graphics card under the foil was super thick paste. i didnt quite understand it so i just took a razor blade removed it all and put on paste.

 

yeah, I think thats what it had, some foil... so right now, my cpu us on some paste and some foil. I'll fix it later. to lazy to take it apart.

 

What are your temps under load now?

 

I have no idea. What do I use to check the temp? My HD gets as high as 57c. Don't have anything to check the CPU.. I looked for some under Vista gadgets but can't find one to check on the cpu.

 

57C on the HDD!?! :O You gotta cool your notebook down dude! That's NOT good at all for a HDD. You should be worried if it goes up to 50C, but 57C... Not good.


Use Core temp or something like that to check CPU temps.

 

70-89c for both cores... is that bad? The fan rarely ever comes on...

 

it's a 7200rpm.. it goes from 37c-57c at times.

 

Those are pretty high, you're fan should definitely be cranking

 

Well, its a DV1000 and a google search shows that this model has a design flaw where the fan doesn't kick it. hmm...

 

That's too hot for hard drive - most have a maximum supported operating temperature of 55C - above that and it's not guaranteed to work correctly.

That's hot. Within specifications (100 C is the maximum), but hot. 70 wouldn't be bad, but 89C is getting close to too hot. If it's running that hot, the fans should be running near-maximum.

It sounds like you really should take it apart again and make sure the cooling mechanisms are set up right. If it's still quite hot, you ought to try undervolting the processor (see Flipfire's Undervolting Guide).

Do you have the latest BIOS update? This sounds like something a BIOS update may fix. It's also possible that there's a recall related to this issue - don't know where to check that other than Google though.

 

As i said, it's TOO HOT! It goes for ALL HDD's out there what temperature limit there is. Not only 7200rpm or 4200rpm, you should know the seriousness in how hot your system is!

You should definately take it apart and fix! Are you really sure that you reconnected the fan when you changed the CPU? Because if it aint turning in you have to have it disconnected when it reaches those high temps!

 

Well, HP gave me a couple of steps to fix the fan issue. The "F10" during boot and reset system to default and save did the trick. Fan is kicking in, and it is now running in the 50's...
