X9000 on 5793 (or equiv) .. temps? (and underclocking?)

I'm sure you're all sick of my posts

I'm hoping to get the new heatsink and 'extreme edition' back plastic so my Sager NP5791 is pretty much the same as the 5793 (also an M570RU) extreme edition.

What temps should I expect for X9000 at 2.8 stock for normal usage (and idle after usage, not boot idle), and for under load?

Just so when I get set up I can know if I'm in the right ballpark for heat.

(Right now I'm using x9000 2.8 on the previous backplastic and smaller heatsink for the T7700, so I'm finding its running really hot, and I don't think I did an especially bad job on the thermal paste. I'm idling after usager at about 55deg celsius (!!) and with load (divx decoding say) I'm hitting 69-72 deg celsius (!!) .. way too hot. I'm hoping the new heatsink will solve all my issues, though I also picked up a notebook cooler I don't want to _have_ to use that..)

So what actual temp experiences do you X9000 owners have?

(I have switched to CoreTemp tool for monitoring, since it shows the temps in the tray and allowsa for logging, but HWMonitor and others all seem to agree on the CPU temps.)

BTW .. anyone know if the x9000 can underclock via software? If I could run it, just for a week or two until the heatsink shows up, at 2.4 I'd be way happy if it saves me some temp. (I'm tempted to put in mt t7700 until the heatsink shows up, butit'd drive me nuts if the new sink shows up the day after I roll that back .. I'm sick of scrubbig paste off the heatsink

 

BTW, what is that chip to the right of the CPU under the square silver heatsink?

jeff

 

it sort of depends on your fan setting, do you have automatic, or do you usually use full blast or even Fn + 3 (quiet mode)?
I have a X9000, and it idles at 24- 28 C, with automatic fan setting.
Now under load, with automatic setting it does get up to 60 C also, and its undervolted as well.
I also have the extreme edition on the back.
But I can get the thing to 80 C when I throw off the undervolt and keep fans on quiet mode and then put under load.

Your under load temperatures are not so high ^^
your idle is quite high though

- the silver heatsink I think is chipset

 

My x9000 (at 3.2ghz undervolted) runs at 30ish idle and 60ish full load.

falcon, what voltage do you run your x9000 at on full speed (2.8 or 3.2, whatever you use)

 

why I'm always idling @ 37°C ??? my T9300 idled @ 28°C..

 

mine's at 1.1V.. below that I get BSODs when under full load, thats at 2.8.
at 3.2 I gotta go up to 1.2V

i guess all the chips are different somehow, I know that a 0.1V undervolt is not so much, but mine cant do any more then that

 

in my 570ru with x9000ES, havent been cleaned for a good 3 months now, i get like 56C in a 30C room after ive been gaming for a good 5hrs.

 

Hmm, mine runs fine (even in orthos) at 1.0125 at 2.8, 1.075 at 3.0 and 1.125 at 3.2 For every other setting it's at 1v

 

I will have to look up undervolting, for sure.

For fans I've always left it at default behaviour, let it sort it out. ie: The fans turn on around 41 deg celsius IIRC, and I assume they'll ramp up as needed. I'm when I'm watchin ga DVD (on the small heatsink still) it hits up to 70 deg I'm assuming the fans are on full at that point

falcon: "But I can get the thing to 80 C when I throw off the undervolt and keep fans on quiet mode and then put under load."
--> ditching the undervolt means running at stock; fans on quiet.. well, they should run themselves up regardless of what you do, when the temp is so high, no? Either way, running at 80 seems risk to me no?

ie: The 'rule of thumb' I've often read is .. 70-80 deg is usually okay, but stressful on your chip; do it for hours on end and you risk killing the chip. Running at 80-90 is the danger zone, shoudl work for awhile but you definately risk killing it. (GPUs can go much higher, not sure what their stress ranges are.) So I worry about runnin gat 70 for a couple hours with a DVD, and running at 80 for a game seems seriously out of whack.

I suspect my new heatsink should arrive Monday, so I'l get better numbers then.

Sounds like we should be running at 70 under extreme conditions, ideally, and rarely past that.

Q: How do I undervolt?
Q: Default fan bevaiour for me .. I assume thats max fans.

I've got a notebook cooler now, but I donm't want that ot be required for gaming or we might asw well use a desktop The cooler is just a frill to keep temps down..

nirana -- seriously, gaming hard and you're at 56 deg? must be GPU games, not CPU

Are you sure you applied the thermal paste correctly and the screws aswell? it seems a bit hot tbh.


Well DOW II, WC3, FC2, Fallout3.

highest ive ever had were 61C

 

oh yeah threres a guide somewhere on these forums that explains how you can mod the CPU Coolers head to be more efficient.

I just cant remember where it is :<

 

notebook cpus are rated much higher than desktop ones. Desktops top out at 75C (junction temp) and notebook ones top out at 105C (Tj) so 90 is ok, but still a bit hot for normal use...

After playing 3hrs of team fortress 2 my ACPI THRM never exceeded 55C (on a zalman cooler as well, but still)

 

Questoin about heatsink -- I ordered it from Sager. I don't know if it comes just brass on the sink, or if it comes with that square of whatever (wax?) already on it.

If it comes with that square of whatever, it should not be as good as MX2 I use, but maybe not too bad. Should I just clean off my CPU and stick with the square of whatever, or should I chip it off and alcohol clean it, and then use my MX2?

(Hopefully it just comes clean and nekked, so I can not have the choice, and just MX2 it. Since MX2 is not conductive, I wouldn't know where on the sync to put it, but I wouldn't have to owrry.. just butter up a square inch and not sweat it.)

jeff

 

If it comes with a pad/paste already on, I'd clean it off and apply MX2 to the cpu die (after cleaning also) like this: Arctic silver guide for small exposed core CPU's

 

I put paste on both the heatsink and the cpu last round, figured that would get it better. (both pretty thin.) Since its not conductive I figure its safer anyway, even if its not perfectly even it should goosh around and flatten when you put the sink screws tightly in place, and if it comes out the side a touch it won't short.. but I don't think I put too much in. (When Sager assembled my unit, they had a good thick 1/8th inch of goo on the GPU.. now _that_ was a bit much

If it comes with the 'hard goo' (wax?) on already.. how much worse is that than spending 20 min to chip it off and apply MX2? (ie: I'll be sorely tempted to just use it as-is, since it'd be a 2 min installation and I'm excited as hell

jeff

 

if you do just use the thermal pad (certainly viable, have a look at temps and see how they go) make sure you clean the current paste off the cpu properly first

 

Ahright, got my heatsink today and did the deed.

The heatsink did come with a pre-applied perfect square of goo so I just went with it. Peeled off the plastic guard over it (and then cleaned off all the plastic crap it left behind ), cleaned off the CPU to a perfect mirror from the previous goo, and put her all back together. I should note the heatpipe was not perfectly shaped, so the screws wouldn't go in right, so I had to bend the pipe just a touch back, and it went in perfect. (Be careful, it bends easy!)

With the X9000 on the old heatsink, just watching a DVD brought me up to 69-74 deg celsius (!!) .. now, I can watch a DVD and barely the fans come on (sits right around 41 the whole time.) I didn't even know you could run this laptop without the fans going till lately

I can't believe the difference (and no undervolting yet.) New panel and heatsink is a _huge_ benefit.

Firing up DoW2 for a few mins and hit 50 deg .. would've hit 80 before.

Whew! Back in business!

nice you def had a hot x9000 i ran fine with the stock old style sink and had no heat issues at all. but great you are where you need to be i only saw about a 4-5deg drop with the new sink vs the old one overall
