Amd Sd 4000+

post #1 of 13
Thread Starter 
hi everyone, this is my first time posting on these forums. I spent several hours last night reading through various threads and couldnt find an answer, so I will just ask directly. Early January I built my first computer. Idid extensive modifications to my a last one, including a new case, but this is the first time I have built from scratch. I have, as the title suggests, an AMD 4000+ San diego. I am trying to overclock but I am having some battles with temperature. I bought and installed a GIGABYTE G-Power GH-PDU21-SC and used AS5. I noticed that my temps did not go down any, infact they may have even rose a little. Its hard for me to be exact on temperaturs because my room temp and therefore case temp varies greatly. My first step was to reinstall the HSF about a week later, using a different method to the heatsink paste. This didnt help so I tried lapping the heatsink with a 400,800,and 1000 grit sandpaper(couldn't find any 600). This made my temps even worse. I was getting about 38C idle with a case temp of 32c, but after lapping I saw 38C at 29C case temp. I removed the new HSF and reinstalled stock but with a stronger fan. This didnt help any so I am back to the G-Power. Right now my Load is running at 48-49 and prime95 can get my temps up to 52c with case temp of 32c. I dont want to overclock unless I can keep the temp under 50, so what can I do?

here is a link to the G-Power

I am resonably certain that i used the correct amount of paste and installed the heat sink correctly. I know AS5 needs a week or 2 to cure, but it is my understanding that this will give me 3C at best, which is not enough. Case airflow is great, I have 2 front 80mm fans and 1 rear 92mm exhaust, as well as a side hole in the case near cpu(no fan because I tried one and it did not change temps at all, and my duct wont fit with the G-power intalled) I am looking for ideas of either a new heatsink to buy, or something I can do with my current setup to help. thanks alot for any help you can provide.

I have a Sandiego as well and my specs are in signature. At stock I was running 38C under heavy load and I was OCing the processor to 2750mhz. I installed the XP-120 last night and my idle went down 10 degrees and I increased my OCing to 2930 and under full load I am at 35-37 degrees still lower then stock. I would try to look for some bios updates for your motherboard or see if you can find some alternate way at reading your temps of the CPU. Those temps seem way too high.

One thing with Opterons if you pump the VCore up they get really hot. For example if I run my Opteron at 1.525 volts when compared to 1.50 volts my load temps will be 4c higher. So have you jacked your VCore up lately?

Your case fan configuration does not sound ideal. Ideally you want just as much fan power drawing air in as you have pushing it out. You might want to consider putting a 120mm fan at the rear if you have room, or you could possibly install a blow hole on the top. You know the old theory, heat rises. Also close off that gaping hole on the side of your case, best case scenario it is doing nothing to increase your temperatures and it doing nothing to help reduce them.

Do us a favor and fill out your system specifications so we have a better idea what we are dealing with. Try these suggestions first. Try closing off that old duct hole first and see what kind of results you get from that. Then try some of my other suggestions.

I dont have the latest Bios for my mobo because the updates didnt seen significant enough to warrant the time and risk, but if you think it would help I can update it.

I did raise the VCore and VRam when I was overclocking, but they have been back to stock for a week or so.

As far as the fan situation goes, the biggest my case holds is 92mm in back. It should be more than capable of expelling more air than the 2 generic(got from local PC store) 80mm in front. The 80mm fans do not directly access outside air, so they dont move a whole lot. The only reason I use them is for my HD, because the mount in my case does not leave room for my 2nd HD to use a HD cooler, so I mounted the 80mm fans to blow over it.

I will try covering up the side hole but I am reasonably certain they wont help anything. I will post back in a bit after I have updated the bios and temporarily covered the side hole. I am still open to other suggestions/opinions from you or anyone else who thinks they can help me out

thanks again.

Ouch if I undestand you right you have no air coming in from outside your case? Thats a big problem because then your cpu HS is using already heated air to cool your cpu which is why you are seeing no change in temps with the changing of the heatsink. It is imperative that you have fresh cool (ambient) air being drawn into the case to create enough of a temp difference to cool the HS. I would advise (if possible) to attach a fan to this hole in the side you are covering up to push some ambient air in to it and see what you got then. But from personal experience it just sounds like your air flow is severly restricted is all. Had to go back and reconfigure my fans in my rig a few weeks ago when I got the fatality GPU cooler because it showed me that my fans were far from adequately placed. As it turns out I had to remove my side panel to get decent air flow due to my hdd rack. Hope it helps.

I think you misunderstood, euphoricmix told me that I needed more exhaust then intake, and I was explaining that even though I have 1 exhaust and 2 intake, I should still be ok because the exhaust is stronger than the 2 intake. And my case originally had a side air duct, but it would not fit with the G-power, I tried a fan instead, but noticed it did not help any. I have disassembled this thing several times and done several tests, and this recent time when I reassembled I left the side fan off because it wasnt helping any.

I havent dont any smoke tests or anything, but I am reasonably certain airflow isnt the problem. My GFX card is at 44C idle, and I dont know what they normally sit at but its core slowdown is at 115c stock, so I am not worried. Maybe this will help you all.
using speedfan I have 4 temp readings
sensor: Winbond W8362HF
Temp1: 32C
Temp2: 38C
Temp3: 37C
sensor: ACPI
Temp1: 36C

Temp 1 is the System Temp, now I dont know if that is inside air temp or mobo temp, but my mobos utility reports it as System Temp,

Temp2 is CPU temp

Temp3 I don't know what it is, but it seems related to processor. Under load it raises and lowers like the CPU does, but it doesnt raise as fast or as high, Maybe Chipser temp?

Sensor ACPI Temp 1 I have absolutely no clue what is.

Also: Updated Bios and Covered Sidehole, Neither helped temps.

Use Motherboard Monitor 5 (MBM5), I believe it will list what those temps are relation to.

From what I understand you used to have an exhaust fan on the side with a duct to your cpu. So your case came configured with 2 front 80mm intake, a side 80mm exhaust, and a 92mm rear exhaust. If this is true because your new Heatsink/Fan does not allow for this setup you eliminated the side exhaust. Your cfm for in-take should be pretty close to that of your out-take. Find out what these stats are and see if you are right in your determination.

A project you can try is running your computer with the side panel off. If your temps decrease only a few degrees *c then your airflow and cooling are probably sufficient. If there is a substantial decrease then you probably have an airflow issue.

The Thermaltake Big Typhoon has seemed to prove to be a very nice HS/Fan a very reasonable price. Most people will see a 4-6 degree drop in temps but from what ive noticed that alot of hs wont get their fully use unless you really tighten thoem down alot. Wire management can also play a big role in helping to lower your case temps and helping those fans you have get that hot air out of the case. If the fans are obstructed or you have agiant cluster f*** of wires they are competeing against themselves. Try getting wires out of the way, tightening the hs'fan a bit more and give the TT Bif typhoon a shot. As someone else noted the best wayt o check your temps is in your bios and speedfan just doesnt do crap for some mobos. BTW the gpower you listed was all alluminum and a cooper hs will disperse alot more heat.

This is mostly correct. The side panel came with an air duct, that roughly stopped around the cpu(I hear on P4 mobos it is centered over cpu). I had to remove the duct because it hits the fan on the GPower. At one time I mounted an intake fan here to blow outside air over the GPower, but it did not help any. I do have 2 80mm intake in front, but they are generic fans from a pc supply store and I dont know cfm. My 92mm exhaust us 32cfm. Just judging by what airmovement I can feel, the 92mm moves the same if not more air than the 2 80mm.. If you think it will help I can try mounting a fan as exhaust on the side panel.

Using AbitEQI(mobo temp monitor) and Prime95 for load

With Side Panel

System Temp Idle: 33C
CPU Temp Idle: 38C

System Temp Load: 33C
CPU Temp Load: 52C

Without Side Panel

System Temp Idle: 32C
CPU Temp Idle: 35C

System Temp Load: 32C
CPU Temp Load: 48-49C

Also, hednik - my wiring situation isnt the best but I am using rounded IDE and SATA cables and I have wires outta the way were possible. I will try to route them around better next time I do major work on the inside. And I cant really tighten the HSF any because its a K8 Clip.

Thanks alot for all your help so far guys
