Need Help!! System way to hot!!!

[Xstatic]

I have a system that i have been running for about 8 months. It consists of a 2100+ on a gigabyte GA-7vtxh+ motherboard useing stock hs&fan. A geforece fx 5200 128, with 768 mbs of pc2100 ram. I use silver thermal paster under the hs&fan. If I leave the case side on it will reach 70c after just a little while. This is without running games, mainly just surfing or lisening to music. If I game with the sides on it will crash after a short period of time. Either a crash back to xp or a reboot.

Can someone tell what is going on? The northbrige gets rather hot aswell. Dont know the temp tho but its hot to the touch.

Any help would be greatly appreciated as i need to remedy this problem.

[crash375]

Where are you getting 70c from? Bios, mbm5, etc.

[shiyan]

there is definitely something wrong.

are you sure the heatsink is seated correctly and making good contact with the CPU core? you used thermal paste, but could you just check to make sure the heatsink is making good contact?

you just need to take the heatsink off and have a look at where the heatsink was touching the core. if it was making good contact, it would have pushed most of the paste off the core, so that you end up with an imprint of the CPU in the paste.

which processor is this, a Palomino or a Thoroughbred A or B? here's how you can tell between those 3: http://www.overclockers.com/tips00173/ or you could tell us the codes, and we can tell you which cpu it is.

does the heatsink get hot during use, and does it burn your hand when you touch it? which heatsink is it?

how is your case airflow? do you have any case fans in there?

[Heatsinkguy]

I had a Pally on stock heatsink and case. The Case has 2 Tornados. When i closed the case, the temp went to 85 degress in the winter..I tried many things and it still went up until i bought the SLK-900. Now my temps are 50 celcius maximum load case closed.

[Sniper.nkc]

Get rid of the stock hs and fan first. Get high performance parts and AS 5 w/ lapping kit if you want cooler temps.

[Xstatic]

Sorry, Yes im useing MBM5 to get the temps.

The Heatsink is makeing good contact with the core, atleast best i can tell. Ive made usre a few times and each time like you said it has a square in the middle where the core is so it is makeing good contact.

I have 1 case fan but like i siad if i leave the case closed it will heat up very fast. What i do now to keep it low is open the side of the case put a 8 inch fan the clips on to my desk and set it to blow in my case. I also have the window open to the room and a big house fan blowing in while to temp outside is somwhere around 40-45f.

This is not a oc'd chip and i dont see why it would get so hot. When I first bought this setup i returned the cpu 3 times thinking it wasa bad cpu that was getting hot and crashing. Have used 3 different PSU's and 2 different videocards.

Bad motherboard maybe? I barrowed a motherboard to see if it was a video card that was makeing me crash but i wasnt monitoring temps at the time. It did crash on the new board so i dont know what is up. Since i put the new card in it will still get hot. I am lookinh to seel this system to a friend but i need to fix the problem as i cant sell a hot system to him.

[archilochus]

If the mobo is not in the MBM 5 list, it may not be giving you the correct reading.What mobo is it? Can you read your temp in your BIOS? Do you get any errors when it crashes? If you leave the door off does it crash, with the fan on it? THE FANMAN:cool:

[dalilman52]

u might need better case flow, im not sure what the climate is in the area u live, but what it sounds like is that u just have bad airflow, try having good airflow thru-out, air intake in the front bottom, and hot air exhaust in top-back or top of case (hot air rises), u also may wanna try making a blowhole directly over ur cpu, that should fix ur high temperature woes


or..u can always get a new heatsink :) a thermalright pure copper cooler is what most ppl recommend around here, with good 92 or 80 mm fan

You said the core is square, meaning its a pally. If I remember correctly, the pally 2100+ is one of, if not THE hottest processor out there.

[Jognt]

1: check HS contact with CPU die
2: check airflow, if no fans, add some.. get that hot air outa there, just add some intake fans, and some exhaust at the back.
3: check if the fans are working.

if none of these help, jumping of a bridge solves all problems...


^note^ not serious there.

I'd still like to know how hot the heatsink gets during use. Touch the heatsink when its running.

also, is there any possibility the motherboard is putting too much voltage through the CPU? it should be running at 1.75v.

[Xstatic]

I'll check the voltage in just a few mins. Right now mbm5 is showing cpu at 41c and i just sat down after leaving the comp alone for a good 8 hours, with a big house fan(2ftx2ft i think) in the window blowing COLD!!! air in the room with the door closed. It is about 38f out side right now. I live in Michigan so it is winter like temp's outside.

Altho 41c seems low that is with nothing running. Just windows and mbm5 and a 6inch circle fan blowing directly into a OPEN case. I have to leave the case open like this other wise it will get very hot.

AS far as the temp reading in the bios it is within a degree celcuis of MBM5. I dont see anywhere to select my motherboard model, unless you can only select it upon instalition of mbm5.

Fans are working but with the tempature in the computer room you have to ware sweat shirt and a blanket to use the computer. Its that cold in here.

Im going to play some Call Of Duty or some UT2k3 to get the temps up and then report back here.

I really really really need to get this fix and if someone could stick with me on this problem for a bit to try to fix this it would be greatly appreciated. Thanks.

[Xstatic]

Temps are same in bios as in mb5 for sure, just rechecked.

Voltage is at 1.744 (400 watt psu)

Cpu fan is at 4500-5200 rpm's

Going to see what the temps get up to while I run some games while I have the room this cold and with the window open with the big fan running.

[shiyan]

That voltage is certainly alright. Did you touch the heatsink with your hand to see how hot it was?

I just remembered something else:

Is it mounted the right way around? The indented part of the heatsink should be over the raised part of the socket. Also the bent part of the clip should be pressing right above the CPU core. If it is somewhat off, the heatsink would not be making perfect contact.

[Yuriman]

I remember my 1600+ always ran in the 60's C. I was using a volcano6, with dual fans. Pallys are crazy hot.

[Xstatic]

Yes the HS is seated corrctly. But the clip bend is not over dead center. Is that a big deal?

The HS is not hot to the touch, not really even that warm. MBM5 syays its at 52c as i type this.

52c is with the case open and a 6inch fan blowing into the open side of the case. I dont have the house fan running right now.

[shiyan]

It does not have to be dead center, as long as it's pressing roughly over the core you're alright.

I guess 52C is reasonable for a Palomino.

[Xstatic]

ya this temp would be great if i could close up the side of the case.

See im selling this system and the person buying it will want the case closed. And with the case closed the telp will get up to 70c and higher.

That is not a reasonable temp correct?

[Yuriman]

Thats pretty bad, go ahead and buy a cheap hsf. I found a solid copper one for $15 from newegg. I know its not that great of a sink, but it has free shipping. That puts it about $8 cheaper than the next cheapest hsf.

Anyone else have any ideas? Im still lost as to why this is so hot.

[Sharkman]

If I remember correctly Xstatic you said you only have 1 case fan. Is it intake or exhaust? Either way with only one case fan you’re probably not getting enough air in or out of the system. This is evident from you having the side of the case open and a house fan blowing inside of it (I’ve done that myself in the past ;) ). I would defiantly suggest getting more case fans. If you look at my sig you will see what case fans I have. With that setup my 1700+ is running 52C at idle right now with a stock HSF and no OC'ing. I have just ordered 2 92mm fans for the front and will be ordering a better HSF soon.

Just thought of something else. Does your Power Supply have a fan on the bottom, i.e. directly over the CPU? If not then the heat from the cpu would only really have one way to get out of the case. True some would go though the back of the PSU but the air flow pattern would make it very hard for his to happen. You can check out the Cooling FAQ here http://forum.oc-forums.com/vb/showthread.php?s=&threadid=178072 to see what I am talking about with the air flow. Hope this helps :D

[mjmnam]

are the case fans pointing in the correct directions? most blow toward you when you look at the sticker.
intake near bottom front, exhaust top rear. buy some Arctic silver 5 or something for the TIM

make sure the FSB and multi settings are correct as well.

[mata2974]

if you had another chip you would just swap it and see if problem is the same, that way you can eliminate a lot of guesswork. 70 degrees is really unacceptable to your friend or he wil be back without a smile on his face:D

[DaWiper]

Isn't it possible it's just the temp sensor that's bad... I had a palamino(xp2000) once and the temp record was 64 dgr. cels. with 30 dgr. room temp(summer) with a crappy glacial tech and no case fans...

[Xstatic]

i dont belive the sensor is bad cause when it reaches the high telps it will crash.

Nad yes i only have the one case fan and i have it set to blow out the back. My PSU also has a fan on the back of it so it has 2 fans in all on the PSU itself. It is not on the bottom like i would want but it is a big one on the back of it.

I have silver paste but i dont know if it is artic3 5 7 blah blah. It just says 10% silver along with other stuff.

[DaWiper]

Well, if your machine crashes with high temps, something is wrong(but that you know already..)

Case fans are just as important as cpu hsf. I tried to use 2 in front sucking in air, and none in the rear sucking out... It was a 100% failure... 10 deg. temp difference with 1 in, 1 out.. I also have a twin fan cpu, dragging out air directly from the case...

Too be honest, I'm out of ideas, watercooling?
If watercooling fails, there are some serious issues with yor setup...

Anyone else?

[Xstatic]

water cooling is not a option. Why would i spend $200 just to sell this computer? I can buy a new cpu and mobo for that.

[DaWiper]

As I said... I'm totally out of ideas..

[shiyan]

I think you lack some airflow inside the case, if both the PSU and the case fan are drawing the air out. Are there any places where you can still mount a fan to draw air into the case, for example the front bottom of the case? If you can mount another fan to draw the air in, then your temperatures should improve.

Also, try putting a different fan on the heatsink, if it is getting hot then the current fan is not strong enough. Maybe as it got older and dust collected, it does not spin as fast as it used to?

Try putting a 3000rpm 80mm case fan on the heatsink instead of the stock fan to see if it helps.

[DaWiper]

If you mount a 80mm fan directly on a normal heatsink the deadspot of the fan will be too big... nearly 50% of the heatsink. Just look at it.... My opinion is that better case flow is the way to go...

[Sharkman]

I have to agree with Shiyan and my previous post. I don't think you have enough airflow though the case.

One case fan isn't enough to effectively get the air out of an AMD system. You have a few things to take into account with just one exhaust fan. Right now the only way air is getting into the system is through all the nooks and crannies of the case. Also the fan has to deal with all the cables in the system to suck the air out and is working harder than it should.

The air from the cpu fan only really has one way to exit out of the system and thats through the exhaust fan. The PSU fans are not that much of a factor because of the positioning of them. Don't get me wrong they do help but they are pulling the air from the extreme top of the case.

I would defiantly get either an 80 or 92mm fan for the front, if you have room for one. Then get a new fan for the rear again either 80 or 92mm. Make sure the exhaust fan is either the same cfm as the front or a little lower. Like 5 or so cfm. This will produce a small amount of back pressure to keep the dust out. :cool:

[DaWiper]

I have seen people adding a 80 mm inside the case to increase the air-flow... Doesn't look too good though...

I got rid of my dust problems by adding a circular piece of filter in front of the intake-fan. In my case, chieftec dragon, there is a actually some room infront of the fan mountings.

I used filter from a kitchen ventilator, it's low denisty, so it doesnt brake the airflow too much....
