OT: your duel core temps?

Yoyodyne wrote on 2/17/2006, 9:40 AM

That sounds a bit hot to me - I've been using a bunch of these lately (x2 3800, 4000, and a 4800) all with stock cooling and I can't seem to get em' above 55 celcius/120-ish degrees fairenheight.

mobo seems to stay at around 25 to 35 celcius.

I do have arctic silver on the x2 4800 & 4000 though - but I'm sure it's not making that huge a difference.

I would think that at 150 your CPU is running hot. Keep in mind that the system has a safe guard and wll reboot itself if it is running to hot.

Jim H wrote on 2/17/2006, 5:07 PM

150F is 65.56C . Might be a bad sensor if the system is stable. My 4800+ never gets much of 40C and the mobo always in the 30s even when rendering. All stock cooling. I have the Antec P180 case which keeps the psu in a separate compartment and I tried to tie off my wiring neatly. My video card also has a custom cooler that blows out the back, that could be helping. I actually though I had a bad sensor because my temps barely change.

That's hot. Sounds like you're using the stock heatsink.

Arctic Silver alone helps to the tune of about 10-12F in many situations. After that, you've got many 3rd party heatsinks. Newegg.com has them all at decent prices, with reviews and descriptions.

My AMD X2 4600+ idles at 38 Celsius and doesn’t go over 55 with even the longest renders. I believe that AMD runs cooler than Intel so you can’t compare dual core temps across the two.

I would say that's hot. My Pentium 4 3.2 HT just got through with a 46 minute HDV MPG render, 90%-95% most of the time, the CPU was 106 degrees F, motherboard 98 degrees F.

Stock CPU fan, Antec case, additional case fan, Artic Silver. Nothing special.

It's cooler than my dual PIII 1ghz, which runs at 118/116 degrees F during a hefty render.

My heat concerns seem to be real.
My CUP temp tops at 151 on Vegas render.
If I play a game and engage my N.7800 GT video card it will spike at 160.

Maybe the power supply is inadequate for my system causing heat with system demand? (It’s a 250 watt power supply with a Pentium D 3.2.)
Or that fact my mother board is not the ideal mother board for a duel core on it.

Coursedesign wrote on 2/18/2006, 11:50 PM

250W is definitely not OK for a dual-core Pentium and a 7800GT card.

You need a bigger PSU, and you need to think through how the heat is moved out of your box, including from the 7800GT.

Check out SilentPC Review, that should give you a good understanding and new ideas for fixing this cost-effectively.

fldave wrote on 2/19/2006, 6:46 AM

Sound like you upgraded the CPU of an old system. Definitely need 400w+ power supply with dual core. Are you sure your motherboard is compatible with your CPU? Sound like you are going to permanently fry something very soon.

JohnnyRoy wrote on 2/19/2006, 7:31 AM

WOW, 250W! You are definitely living on the edge. Go to a PSU calculator like this one from eXtreme and see how much power you need. I would bet you need at least 350W+ minimum. Then add 50W for safety and get a new PSU. I would agree with the others. Don’t get anything smaller than 400W for a dual core with a 7800GT.

Fldave:
Measuring the temp, there must be no delay in looking at it after the render as it immedeately nose dives. I do not beleive 105 F during the render ,in fact, that is impossible unless you have liquid nitrogen cooling. With a P4 you will be around 120 to 140F during the render then drop down to about 98F after. If you have a 7800 card you better hook and air conditioner duct to the computer. 150F is too much.

JJK,

I thought that looked pretty low, also. Just looked during the render and it was 134F. Stopped the render, and 15 seconds later it was 111F. That was quick! I stand corrected on the P4.

Dual P3 of 118F is accurate, as I use to use Motherboard Monitor on that machine. I don't use it on the P4 as I want all possible cpu cycles going to my editing/encoding.

Ok I ran the PSU calculator and it came back @483w

500w power suppy would be in order; with a small turbo prop for cooling...

Thank you all for the help.

Very cool. What kind of system? And what kind of cooling?

Jim H wrote on 2/20/2006, 7:04 PM

I've got my specs in my profile, not sure how others can see them though. I've got a 4800 2X, ASUS SLI Pemium mobo, ASUS GTX7800TOP video, 2 gigs ram, couple of WH HDs in a Antec P800 case with Antec 500w psu. All stock cooling - three 120mm fans on low settings. Stock passive chipset heatsink, and rear venting video card fan.

Quiet as a mouse and cool. Too bad I have my last two workstations whirling away right next to me with my two boys working on them. It's nice after they go to bed...very quiet... I

"500w power suppy would be in order; with a small turbo prop for cooling...

I've got a machine loaded with 8 drives and some other power hungry stuff. This was really taxing my Antec 420 watt supply (it was loaded so heavily, it would take a few tries before it would power up) so I bought a Silverstone ST65ZF 650 watt supply. The thing is noisy with it's 80mm fan, but the voltages are rock solid and it effortlessly spins up all 8 drives at bootup.

Just after I got my ST65ZF, Silverstone came out with the ST60F 600 watt supply with a 120 mm fan. Lots of power, very quiet.

Both of these supplies have an incredible build quality and they have FOUR separate 12 volt rails with a total of 55 amps. They're kind of pricey, but I highly recommend them. A lot of strange Windows/computer problems can be traced to flaky power.

I have a Intel P-830 3.0 dual core CPU with an Asus motherboard and it runs HOT while rendering. I can easily hit 77C.

Doing a little reseach I found this link which provides max temps for all CPUs http://users.erols.com/chare/elec.htm

And this site http://www.heatsink-guide.com/ which states not to worry about the temp on an Intel CPU because the CPU just slows down when it over heats so there is no damage to the CPU.

Also found a very handy free little program which provides numerous sensor readings, hard drive conditions, temps, etc.

Even though some may say these early pentd's are ok at that heat, you still want to bring it down. You don't want your proc throttling when you can easily help the situation.
i have an x2 4400 and the amd duals run a lot cooler (30c idle 46c full bore), but yes, the early pentd's run hot.

Listen to some of these others, get a decent/efficient 3rd party cooler and arctic silver 5 (just a little, about a grain of rice size - just enough to fill any gaps).
Then, before latching down, put the hsf on the cpu (don't take it off at all at that point from the cpu) and semi-lightly press down and slowly slide it around a little bit (spread out that arctic silv), then latch.
Again, on't overdo the hsf grease.

here's a link to a better hsf:

I’ve got the ZALMAN CNPS9500 on my system and it’s running at the slowest fan speed so it has plenty more cooling powered than I need for my AMD X2. I’d bet it would help that hot headed Pentium keep it’s cool. ;-)

Definitely use Arctic Silver between the proc and heat sink. On my old system, all I did was add Arctic Silver to the existing stock heat sink and it brought temps down by about 5-8 degrees. The best cooler in the world won’t work if you don’t have efficient thermal transfer.

steveh714 wrote on 4/3/2006, 8:44 PM

Got a Zalman CNPS9500 installed over the weekend. Absolutely unbelievable difference!

Rendering temp has gone from 77C to 53C.
Normal usage temp is now 43-45C!

Thanks JohnnyRoy for the Zalman fan idea! Just bought mine from Newegg and used arctic silver on it, for my 478 factor P4 and WOW

CPU temp dropped from regularly being 72-76C (wayy to hot) to now
running 55C, a huge improvement. No more lockups.

btw Grab the free "Asus PC Probe" utility (google around for it), works great, better than the speedfan one imho .. shows all voltages and temps..

Speaking of liquid nitrogen... I went out and bought one of these today! Best cooling on the market... now I am just waiting on enriched uranium quantum processors to flood the market and I'm set :)
