AMD X2 3800+ running too hot????

[Oyeve]

Hi all. I just finished putting together my new system. It consists of an ASRock 939SLI32-eSATA2 mobo, AMD X2 3800+ dual core, six HDs, eVga 7800GT, one sata/ide controller card and an X-FI soundcard. I opted not to go with the stock HS/fan for the chip and purchased a Zalman CNPS 7000B-CU HS/fan. The install went fine, installed XP Pro and all that jazz. I have two front intake fans blowing over the HDs and a rear outtake fan to suck heat from the case. My PSU has two outtake fans. Other than the mobo, cpu and video card the case and all were from a previous P4 3ghz prescott system with an ATI X800 XT. On the old system with the stock HS/Fan the cpu temp was 41c idle and 53c at load. On this system, with the big Zalman HS/Fan I am getting 53c idle and up to 67c load! This, IMO, is way too high! Is this HS/Fan crappy? I didnt use the thermal paste that came with it but instead use AS5. I put on a dab (rice sized, maybe a bit more). Is this normal temps for this system? Should I remove the AS5 and use the stuff that came with the Zalman? Everything in the bios is set properly and the fans are running at full speed. I decised not to use the speed regulator for the Zalman as I wanted it to spin the fastest and let the bios control the speed. Thanks.

that sounds pretty messed up man. is your case an ATX, MATX or full tower... If its full i might be able to see how that could happen but if its ATX or MATX that doesnt make any sense to me. IMO its the Heatsink and the fact that you have so many HDs and a 7800 GT in there. But damn i have never seen that before unless it was OCed. Anyone else have any ideas, thats all i got.

Check and re-check the seating of your HSF.

I used to have one of those before my CNPS9500 and I never saw anything over 40*C at load.

I would recommend using the speed control that came with it. Its there for a reason.

Besides, the difference between high RPM and low RPM is 2*C

I always use stock HSF.

try using stock that came with it.

The stock one I ahve is our 29 Celcius idle, no higher than 44 load.

This is the stock heatsink on a 4400+ X2

I have 1 HDD a 7800gt (evga overclocked edition) 1 dvd/rw 3 case fans (2 120mm and 1 90mm) and the athlon 3800+ x-2.
on the evga sli motherboard.

current temps...

7800gt ->38 C (gets up to 67C when im doing some serious gaming)
motherboard -> 24C
CPU-> 26C (running 2 instances of Prime95 from the time i went to sleep to when i woke up it was at 44C)

I have a thermaltake tsunami dream case, its pretty big, and not alot of stuff in there...
I am using the stock heatsink/fan that came with the processor...it was a beast to get it on lol but i prayed and it worked LoL hence the sig.

If you have 6 hd's in a microatx cae LoL im still not sure it would hit the temps your talking about. the X-2's should run alot cooler than the intel chips...

So here are my speculations.

THIS SEEMS MOST PROBABLE.....
it's possible there is a thermalpad between your cpu and heatsink. follow the instructions on the page and it will explain what to do about that.

Possibly, you put on too much arctic silver 5. thermalpaste is designed just to fill in the indentations on the heatsink and cpu creating an absolutly smooth contact. Sometimes people make a buisness card's amount inbetween and they get some crazy readings. You want to see the color change on the thing but you dont want to be able to see it raising off its surface even a buisness card's width when you look at it from the side.

here u will see, the size of a "short" grain of rice..or 3/4 of a BB. use a credit card to thin it out. also it has some nice diagrams showing what your actually trying to cover underneath the cpu's heat spreader.

when you apply it..try to twist just a little with the heatsink, thining it and spreading it..and forcing it into the microscopic cavities.

the reason i went into all this was because you said you used a rice size drop maybe a little more....with arctic silver less is more.

another thing i can think of is... Your cpu's temperature diode is messed up.

try reapplying the arctic silver (will work better than the goop that came with the heatsink/fan you purchased) and do it in the exact exact exact way they specify on that website. also, you cpu will drop 5C over the next 2 weeks after you have used the arctic silver. Be sure to follow the instruction on powering down your machine so that arctc silver can do its weird chemistry magic.


best of luck to you.

Well, I took the HS/fan off, it appeared to have too much as5 so I cleaned it all off and put the correct amount on, same results. The HS/fan is spinning at ~2600rpm. The GPU is hot, may have to replace with an after market. Any suggestions?

 

[Arkane13131]

what video card do you have, and how hot is it running?

i know u have an evga 7800gt...but which model? mine is the one thats 470mhz on the core and 1100mhz on the ram.

 

[Arkane13131]

also...if your gpu is running lets say 70C on max load...wait 2 weeks for arctic silver to start doing its magic....that drops to 65c and under....your just fine.

im a little confused...are u talking about your cpu or your gpu?

The CPU. I mention the GPU cuz it feels very hot and may be adding more heat to the case. The case is a Lian Li PC-62 mid sized tower. I have the 470mhz on the core and 1100mhz on the ram.

I'd take one of the intake fans and put it in the rear of the case. Negative pressure FTW.

You mean have all fans blowing in? (exept for the PSU, obviously) Wouldnt that just swirl arounf the hot air within the case?

 

[Arkane13131]

your gpu shouldnt be heating up your cpu. gpu will run hot..that evga card same as mine... 67C full load. however...if your cpu is stil climbing higher than 50C id just put the stock heatsink/fan on and see how that works. dont use arctic silver on it either there is already a square of wax type stuff on it. 2 people here running x-2's different idle temps but the same on full load of 44C using completly stock heatsink/fan.

Well, im not taking apart the system to put the stock back in. Maybe i'll get a faster fan for that will fit the Zalman. I did replace the rear outtake fan and noticed about a 2c diff but still 50-53c idle. Tried playing HL2 for a couple of hours at max settings, rebooted real fast and went into the bios to get the heat reading and it was at 57c. May the Bios reading is wacky. Its version 1.00 so maybe being its a new board and new bios there will be an upgrade.

Well, after a few days my system is 44c idle and hit 54c after playing NFS:MW for a couple of hours. I think this is pretty good considering I have 6 hard drives in the same case as well as the 7800GT. Thanks for the help guys.

No?

Two fans on the back blowing out. One fan on the front blowing in.

where are you getting the temps from? the board or a probe? i have not been using any type of temp gauge on my current rig because my m/b is known to f*ck up temps, by ~20C. just a thought.

also, 6hdds, what type?

I'm getting temps from the board. The HDs 3 Maxtor Maxline III 300GB SATA drives 2 Seagate 7200.7 200GB PATA, 1 Maxtor 250GB SATA.
