Overheating Problem...

[Shocker838]

hi, i have an asus a7v133 mobo with a 1000mhz chip, and the asus probe tells me i am running at 66 C / 150 F for the chip, and 26 C / 78 F for the mobo itself, i think the chip is kinda running hot, so any suggestions on fan placement or cooling sugestions would be most helpful.

i tried that white cooling gel stuff, but i wasnt too sure how to mount the stuff so i removed it. the chip itself has feet to take the pressure of the fan so the heat sink is risen up a bit from the chip itself, shoudl i build up the gel untill it touches the heat sink or what?, thanks alot for the help "Less work more network" (HP) -- its so catchy

I have an AMD 800 that runs at less than 80 degrees F. I think you definitly want your thermal grease to touch your heatsink but don't get so much that it oozes out and gets all over everything. For fans, I have the one in the PS, the one on the heatsink, and an additional one mounted on the back of the case directly across from the processor. Seems to run nice and cool all the time. Might get an extra fan and make sure your heatsink is touching your processor where it's supposed to. The heat can't dissipate off the processor unless it's actually touching the heatsink. If that's not possible then i suppose thermal grease build up is an ok way to go.

hmm, what kind of an 800, and external temp sensor?

cuz I have a Duron 800, and has watercooling attached (see pictures at

http://www.kb244.com

under the Misc section)

and typically if it's around 70F for the water (room temp around the same) the Duron is anywhere between 89F to 95F

of course that's without a peltier involved, but does have that Artic Silver Thermal paste involved. Karl Blessing

Sometime the sensor on the mobo are not setup for the most accurate readings. i have an epox mobo running a stock 1 gig t-bird in a midi tower case, with a stock cpu hsf and one extra case fan exhausting warm air from the front. it runs at a constant 44c which for this chipis within its normal operating range (40c - 60c).

there are several shareware products that measure cpu temp. the two main ones are sandra & mother board monitor. i think they are both available from zdnet.com. try these as they may give a different reading than your prog does. to put this into perspective, sandra says my cpu is 240c where as mbm says it is 44c. this reading coresponds to the reading obtained in the bios of my mobo.

if this fails try

http://www.overclockers.com

the guys in the forums are 'experts' in the feilds of reducing heat in cps. some of there recomondations may seem extream but they will all be considering.

good luck

Thanks for all the replies, i really gotta get this problem fixed, i will try downloading the 2 mobo monitors and if its still running hot maybe check the websites, thanks again. "Less work more network" (HP) -- its so catchy

 

[brendanhedges]

I would and quick. your chip is too hot thats for sure.

remember faster and more stable comps have cooler cpu's inside.

by the way there are several forum entries in overclockers.com about the correct application of artic silver.

hope this helps

Hey Shocker,

I have an AMD 1.1 that was running hot. It would crash above 138 degrees F. I installed a case fan, a bay freezer, a slot fan, and installed a "Super Orb". It would still get hot and crashed. Finally I "underclocked" it to 966 and lowered the core voltage to 1.5. Know she works fine, and I don't miss the 133 off the top at all.

Hope this helps

I have an Athlon 800 with the thermal probe mounted on the side opposite the heatsink (obviously). The program I use came with the motherboard. It lists the system temp at about the same but a few degrees less. Is this too good to be true or something? That's what I am getting from your responses anyway.

To brendanhedges: Why would you give any recommendation for a program that says it's at 240 degrees C? That is obviously the incorrect measurement. Justin

 

[brendanhedges]

justin my point was this.

dont just belive a reading because a piece of software says so. use several to get a overall veiw of the systems temps. and just because it indicated my cpu temp was higher than it actually was, doesn't mean it will on everybodys cpu.

Back to the "feet" on the chip, I've seen those, but they were on the underside. Besides, It doesn't seem like they would put them there and not allow the sink to touch. Furhtermore, you may not have the clips in the right place...the sink may be on backwards. If worse comes to worse, put enough greese on it to bridge it, like you suggested. On the Asus that I have, the capacitors were in the way, so I had to cut the sink to get it to work. If you put the sink on backwards, it will definitely not touch the CPU. Make shure that those feet are supposed to be on the top side, and the greese is only supposed to go on the shiny part of the chip.

 

[Shocker838]

the feet are on the chip itself, not the heatsink...yea i am looking into other system mons, but i think my chip may have been bad to begin with...one thing was it would get alot of stop errors while doing heavey operations, hence, probably from the heat, i am guessing, or just a bad chip, maybe a little screwey or something, i dont know...

also, i am prob gonna pick up a new full ATX case, one that will enable me to get around in there better, and position fans around, i am gonna stay away from thermal grease for now...also, any suggestions on cases, or i am thinking of getting a new heatsink, maybe bigger, any suggestions on that? thanks alot for the help guys. i really appreciate the replies. i hope this helps others too because i know cooling is a main concern.

btw, i like the idea of underclocking...might try that if worst comes to worst...but who knows. "Less work more network" (HP) -- its so catchy

Hey Shocker,

Don't be afraid of the thermal grease. It serves a purpose. Just put enough on to barely color the chip white. All it does is fill in all the microscopic holes in the surface of the chip and heatsink, giving better heat transfer. It squishes into an ultra thin layer when you snap the clip into place. The feet are on the chip to hold the heatsink in a flat position. If you accidently were to put the heatsink on a little crooked, and the feet weren't there, you might have only one edge of the chip touching the heatsink. That would be bad news. AMD also says that uneven pressure on the chip can cause irreparable damage. The entire surface of the chip, (on the AMD it's the little raised portion in the middle), is supposed to contact the heatsink.
Incidently, my underclocked 1.1 is still running solid. Playing high end games and multitasking without a single crash. It will know run at temperatures that before would make it fail, (144 F.) Lowering the core voltage must make it considerately more stable.

Bye!

In my opinion you shouldn't have to underclock your processor in order to get it to run stable and/or cool. If you find you have to do this then I say you don't have something set up right or it's a bad chip. Just my 2 cents. Justin

that, or the case is poorly setup, to where airflow cannot easily move through the case, for examples, you may have a heatsink and fan on the CPU, but if you got ribbons, wires, all that junk, and no chasis, or chasis fans that are all dust infected, you will not have the proper airflow to get the hot air out of the case, instead it'll just keep blowing that same hot air back onto the heatsink

a typical flow design on a mid-tower

that is the most common recomended airflow, and that the pathway should be clear or as much as possible. also keep in mind that the PSU fan has to be dustfree or you get more build up of heat, and always remeber heat travels up(in case you try to thing of some better airflow design)

just be sure that if you want to set up fans, that the air should flow in one direction for efficient cooling, I've seen some special &quot;cooling&quot; cases, that has about 18 fans it in it something, but they all just blow in different directions, and it screws up the airflow.

also check out overclockershideout.com for that new Core heatsink, and further more if you want to get chasis fans, I recomend those made by Sunnon (I have 3 120x120 sunnon fans, in the picture of my water cooling system in the URL up above in prev post) Karl Blessing

oh also, be sure to use Thermal Paste, like at overclockershideout.com they got Artic Silver II, one of the best kinds you can apply to your CPU, and almost every OC or power user will use thermal paste, (heatsink may not always touch the die without it, thus creating a very dangerous heat pocket just between then) Karl Blessing

You can also get copper shims (about $10)to put between the chip and the CPU cooler to avoid any nasty problems with the thermal paste. Read those forums to get the best advice on using the paste and the best coolers.

 

[Karl Blessing]

if its the Duron or Tbird ,get the DTS-400 Shims also at overclockershideout.com

hehe, if you were to just get what you needed from them, I would sugest getting the Core Heatsink kit (75$)

it comes with that big heatsink, Artic Silver II thermal paste, Copper Shim for the type of CPU you have, steel mounts, etc

anyways this is the URL for it

guys thanks for all the help, i think i am going go with &quot;the orb&quot; heatsink/fan from coolerguys.com, the one with 2 fans in it, pumps out like 44.1 CFM's of air...its looking good, and maybe that case from coolerguys.com (THEON Cyclone 5000 Ultra Rev2 pumps out like 227 CFM's)...and a purchase of arctic thermal II...hows this sound?? &quot;Less work more network&quot; (HP) -- its so catchy

1) you must use thermal paste on the CPU, without it the heat transfer between the chip and the heatsink will be seriously effevted.
2) The small raised billet in the centre of the processor is the contact area, all the heat passes through this very tiny point.
3) Just apply the smallest amount of thermal paste to this raised area! not on any other part of the processor.
4) Your most important consideration is to lower the max CPU temps you are getting. IMPORTANT RULE most standard cases were not designed with hot running T/birds in mind. you will have to modify the internal cooling.
COLD AIR IN (ambient temp) HOT AIR OUT!! position an 80mm case fan near the CPU to either blow cold air onto it or take warm air away! draw yourself a simple air flow diagram of what all your fans are doing! try to keep the airflow in one direction!
5) when I first fitted my 1.2 (not clocked) it was maxing at 66oC, now with the addition of two standard 80mm case fans strategically place my max is 43oC (that is with an ambient of 30oC) I didn't cut any holes in the case or fit a massive heatsink and fan, I have one 80mm blowing at the heatsink at about 7cm from the side, the other I mounted in the power supply, which on my system sits above the processor, I turned the processor fan upside down so that it sucks air off the heatsink whilst the 80mm in the PSU TURBO sucks off the processor.
6) So think of air flow, COLD IN, WARM OUT!! There really is no need to underclock the CPU, or fit massive heatsinks with Delta fans that make your system sound like a Hoover on steroids. Believe me the solution to your problem is simpler than you think!!
