System heat
« on: August 26, 2004, 02:19:17 PM »
Heat seems to be and issue with my system, got 3 fans bringin air in and 2 (powersupply fan counts as one) blowing it out. Also has holes cut in oppisite side from side fan. Got the side panel off and a external fan blowin on everything now

Doesn't make sense cause my son has identical system but it's runnin as much as 10 degree's cooler with the stock fans and stock heatsink?????

Gettin right around 50C runnin AH now. Used to go up to 68C while runnin AH.

Replaced stock heatsink with a swiftech MCX462-V. Using a standard 80mm fan on heatsink.  Dropped temp about 5 degrees.  Using ArcticSilver #5 on CPU.

Note: my ATI9800 pro fried and the replacement is otw. Have to run my old 9000 pro for now. Heat seems to follow me around on all my systems.  Thinkin of gettin after market VID card cooler and a monitor fan :(  

Live in the high desert of Nevada.

MB Asus A7V8X-X
CPU AMD 2500+ Barton
RAM 512
VID ATI9800 pro (fried) replacement OTW so using older 9000 pro right now.

OS W98se

Sound SBPCI512

CPU temp is running at 43C right now.

Runninng Asus Probe software with the  cooling software activated.

Any thoughts or recommendations?

Make sure you use thermal compund of some kind on that heatsink. Try getting an aluminum case, my new case dropped my temp significantly. Put your system on the floor, it is usually cooler than the desktop, but make sure air can circulate around it.

What is the ambient air temperature?

I used a Thermaltake Silent Boost on the 3000+ XP (overclocked by multiplier to 3200+) and the highest temperature I could manage was 51C.  At idle it runs at 41C.
This is with an ambient of 79F.  I used Artic Silver 3 for the heat sink compound.

I have one front 120mm intake fan, a 120mm exhaust fan and the power supply exhaust fan.  The case is the Antec SLK3700BQE with an Antec 480W TruPower supply.  The video card is an ATI 9800Pro 128MB card.

Thinkin the temp is over 80 in here :(

And the system is close to a window (maybe 2 feet away) that takes allot of afternoon sun.

My son's system is close but facing another direction (about 90 degrees to mine).  With mine the side fan is facing the window.

Hmm may have too many bringin air in and not enough blowing the air out?

If the case gets pressurized it kills turbulence in the case, which could cause hot spots.

But you said you had the sides open and a fan blowing in as well.  If it gets hot doing that, I would say the heat sink is not installed correctly.  What kind of heat sink compound did you use?

Arctic silver #5.

Temp while online usually reaches right at 43C according to Asus probe software.

While online in AH usually reaches 48C to 51C.  Again according to Asusprobe Software.  MBM5 gives me a temp about 3 to 5 degrees lower but goes up quicker???

Note: am running the cooling software during all this.

Note: temp in this room right now is around 75 F and Comp is running at 39C.

Thinking room temp has been too high for awhile now.

Wrag, run the system with the case side off and check the temperatures.  That will give you a baseline to determine what the minimum CPU temperature is that you will see.  Is the full load CPU temp 68C or 51C?  68C is WAY too hot.  51C is not that bad.

Can you find the CPU core voltage on your MBM5 readout?  I'd be very curious to know what it is.  A 2500+ should run at or very close to 1.65V.  It's also possible that too much thermal compound is applied to the heatsink.  Remember that the purpose of thermal compound is only to eliminate airgaps between CPU die and heatsink base.  Thermal compound has better thermal conductivity than air, but is much worse than aluminum or copper.  Using too much can actually insulate the CPU.

Also, a rule of thumb is to have more exhaust fans than intake fans.

Says vcore is 1.728

Temp is pretty steady full load of 45C while online in AH today.  Thinkin part of the problem was room temp.  Is much cooler here today then it has been.  Outside temps in the high 70's.  Inside temp also lower.  A/C ran some of the time but not like normal of all day long when on.

Current temp is 39C.

Processor runnin at 1833 max is 2250.

External clock at 166 max is 333.

Max temp recently is right at 51C.

Base of heatsink is pretty hot, while the cooling fingers/spikes are quite cool.

Went into bios.  Both vcore and (dangit can't think of the name) were set to auto.

Set vcore to manual and vcore is now 1.664.

CPU fan runs at a pretty steady 2700 rpm.

Set (can't think of the name) to manual and 333 from auto and 166.

Temp has dropped to 37C ???
