Opteron 170 w/ Venus 12 PROBLEMS

I?m having some temperature problems with my CPU.
I have Opteron 170 with Venus 12 HSF. The rest of the system is as follows:
Opteron 170 X2 Core
HSF Venus 12
Asus A8N32-SLI
2Gb Patriot ram
Raptor 74GB
Case Wavemaster

The temperatures I?m running:
Idle 45C
Load under Prime95 torture test after 30 minutes 56 and rising.
This system is not overclocked. I have tried twice applying Thermal Compound that came with HSF, after cleaning of course, and I get same results. I?ve also bought cleaning solutions by Arctic, and their Artic Ceramic compound. Cleaned the CPU and HS very well, many times. Applied Artic Cemamic as per instructions (3rd time I?m applying it, so I should be good at it). Well, and I still get similar temperatures.

Any advice? Anyone running Venus 12 on Opteron? What are your results

Thanks
 
What does your case look like? Intake vs Exhaust fans, also are you using the HSF that came with the 170? And are you referring to AS5? Also what video card do you have and do you have stock cooling or an aftermarket cooler on that?

Hi, case looks like this link

Case has two intakes fans and one exhaust fan.

VIdeo card is Nvidia Quadro FX 3400 (Temperature around 60C) Stock Cooler on it.

under load, is the cpu cooler hot to the touch? be careful...

I used as per the instruction. Size of a rice, maybe a little more.
Previously, with Venus 12 thermal compound I've used more and covered more. Artic instructions claimed that corners don't have to have thermal compound since most of heat gets transfered in the middle of the chip, so I did that.

I'll check the how it is when I get home, see if I can fry eggs on it 🙁 lol
 
How are your ambient room temperatures? If you are in a 30C room, your case and CPU temps will be much higher than if your in a 25C room.

How do your Room, Case and CPU temps compare?

As an example, Im using a slightly undervolted Athlon XP 1700+ at stock speeds. 24.6C room temp.... 28C system/case temp.... 41C cpu temp (fluctuating CPU load while watching TV so a little work)

A few other points I can think of:

How dusty is your case? Give it a little spring clean, gently wipe fan blades, fish out dust bunnies from between fins in the heatsink. This probably isnt your problem but its an idea at least.

How good is the contact between Heatsink and the CPU? Apply AS5 as normal, place your heatsink on as normal and leave it for a little while (few minutes max) then take it off. You should see a nice large imprint of AS5 on the base of the heatsink. If you dont, you may be installing your heatsink improperly or the mounting mechanism may need a little tweaking.

Hope Ive gave you some good ideas to check out and I hope even more that you find your solution. Buying a newer, bigger and/or better heatsink should be one of the last options you look at, however we can also help in that department if you need it 🙂
 
My A8N32SLI reads crazy high temps too, my 148 idles at 44c and my 170 at 49c.

All this at def vcore and an alpha 8150m1 cooler.

If its stable don't worry about it.

 
Elcs, I'm in NY and it's pretty cold out now, so my room temperatures isn't really hot. Not sure exactly what it is.

My cause is brand new and all components except for sound card are new, so there is no dust, I wish it was that easy to fix.

Regarding re-attaching HeatSink, I've done it twice with original thermal compound that came with Venus 12, and each time I saw it was the right amount, except the 2nd time I tried it, I actually put too much, but it didn't change the temperatures.

A newer heatsink, eh, is a possibility, I want to try to solve it other ways first, don't want to spend more money, I think I've spent enough.

PCclark99, wow, those temps are very high. My computer has been on for 20 minutes, and I've only been web browsing, the temperature wet up from 38C to 47C practically at idle.
A8N32SLI is a hot motherboard by itself, and if it heats up, it doesn't cool very fast, unless you have a perfect and strong airflow in your system.
However, regarding CPU temps, I've seen people report NORMAL idle and full utilization temperatures. When I say normal, something below 40C at idle at least.
It is possible that motherboards sensor is off, but I wouldn't want to take a chance on guessing, since I maybe be running my CPU at max, to create any thermal damange. Now, that would really suck.

Thanks for all the help. I'm gonna try Prime95 Torture test "In-Place Large FFTs" on both cores, and report with results.
 
Here are some temperature tests I've ran.
Venus 12 set at 3246RPM. 5200RPM is max. At Max it sounds like JFK Airport. Setting it to Max drops CPU temp by 2C and is too noisy. The problem isn't here.

6:54 pm (Start of Prime Torture test "In-Place large FFTs" both cores.
Prior to test temp:
CPU - 48C
M/b - 39

6:57 pm (3min)
CPU - 54C (+6C)
M/b- 40C (+1C)

7:07 pm (10min)
57 (+9C)
42 (+3C)

8:15 (1hr 19min)
59 (+11)
42

When I opened the case, and touched Heatsink, it wasn't exactly hot , but very warm.

I guess I'll give it another day, and reset again with a little bit more of Artic Ceramic, if anyone has any more ideas, please let me know 🙁

Thanks

Ok, So I've reset my heatsink for the 4th time now. The amount of Arctic Ceramic I've applied previous was just perfect, so I did the same thing again.

This time instead of manual control of FAN RPS, I've attached supplied thermometer with Venus 12 to underside of HSF. It monitors the temperature and adjusts the speed accordigly.

PClark, this is where I advice you to look into you system setup. You probably do Idle at 49C and that is HIGH!!!! I don't believe A8N32-SLI is reading temperatures wrong. Since boot up after I re-applied thermal compound, the fan RPM, thru Heatsinks thermometer, went from 3000RPM to 4687RPM at 46C, and that is at idle. So temperatures are indeed high, Terrible. Let's see in few days how much it drops, since Arctic Ceramic has 24 hour break in period or few heat/cool cycles.

 
Have you tried running prime with your case open? I have a feeling your case isn't removing heat fast enough since it has only one 80mm fan for exhaust and if your case is silent meaning your fans are running at low RPM's, then that one 80mm exhaust and PSU fan (albeit low RPM fan) won't be enough to remove heat from your case. That is why I will only use cases that use 120mm fans for front and rear and a side fan reduces temps about 5c on the CPU in my experience.
 
do u have a case that orients the motherboard upside-down? in other words, is the CPU closer to the bottom of the case than the top? [edit: nevermind, wavemaster]

(i think i read somewhere that that motherboard wasn't designed to operate upside-down. the coolant in the heatpipes won't work that way or something like that.)

try plugging the cpu fan directly to the power supply and/or try a different fan altogether. make sure cool 'n quiet is disabled in BIOS.

u check to see if heatsink is hot to the touch yet? if it's only mildly warm, i wouldn't worry about it.
 
sumyungai, I will try running prime with my case open later today or tomorrow.
About hot air, I also think you're right.

I think I have more than one problem now, not just the Heatsink, but airflow within the case too. Wavemaster's airflow is terrible, unfortunatly I only learn of this after I bought this case. Reviews I read were very good for the case. The Problem is that at intake, there are a lot of holes, but they are too small. So I don't think enough air is able to go thru, on top of that, two intake fans are not exactly right by the holes. So They are not sucking as much of cold air as needed, and possible recirculating air inside the fan. This also maybe building resistance inside the case for the ehaust fan(ie not enough air coming in as it's blowing out) When I tried opening the bottom panel (it's on a hinge) the temperature for motherboard dropped about 3C, and for CPU about 2C.
All of my fans are running at full speed. Especially the Venus 12 monster, is authomatically adjusting itself to high RPM with it's sensor, because it's HOT!!! Spins from 4400RPM to 5200 RPM, under idle/mild use of computer. And this thing is not quiet. From all the reviews I've read on Venus people setting it to middle about 3000RPM, did a better job than stock cooler.

I wish i knew better to use a case with 120mm fans. Unforunately i can't modify this one to fit 120 fans.

Heckler, HSF is plugged directly into 4 pin molex from PSU. It's to powerful to be connected to m/b so there is not even that option. Cool and Quiet is disabled. Heatsink is not exactly warm, but I'd call it very very warm. At this stage I think I've ruled out errors in M/B's sensor, since Venus 12's sensor makes it speed like a JET plane.


I'm considering these options for the case modifications. 'Some' of these options has already been discussed in previous Wavemaster threads I've found.

- Cutting a hole/ or drilling at the bottom of the case, so that exhaust fan could draw more cold air, and reduce resistance, but I might be ruling this option out since exhaust fan might not be able to pull air from that far, and there are minor openings on the backside of the case, this is where it's more likely for lacking air to come in, during resistance.

- Drilling larger holes in the front, or cutting thru existing holes to create a few rectangles/lines where holes are. Improve intake ability?

- Drilling Holes in the side panel, and installing additonal intake fan, to blow cold air a little below and to the right of CPU, with top left quarder of Fan being being above CPU.

Then, I guess I'd have to look at optional heatsinks :disgust: ehhh so complicated.
 
I don't think you need to drill a hole in the bottom of your case. Your problem is lack of exhaust. Therefore, you should get rid of that rear 80mm and drill a bigger hole and fit a 120mm fan. And then use that 80mm fan on the side panel where you will need to drill another hole. And that should fix most of your trouble. As for the heatsink, the Venus 12 is using an 80mm fan and therefore will be loud especially cooling a dual core. If you want to minimize noise, try using the Thermalright SI-120 with a 120mm fan spinning at around 1300rpm and maybe use the same type of fan for the exhaust. While you're at, you should might as well cut the grill holes hindering your intake.

I did this with cheap cases that cost $12 on newegg a while ago before I knew a lot about the importance of airflow and it turned out pretty well. Good luck.

Well, I had the same processor with the same cooler previously running at the same clockspeed and voltage on a K8N Diamond SLI board. The temperatures ran a good 7C cooler. And it wasn't a misapplication of thermal paste. I am pretty confident some of the A8N32-SLI boards have some accuracy issues with CPU temps.

120mm won't seem like it will fit in the back of the case 🙁. maybe two 80mm will, but I will have to cut 2 new openings, and cover opening of existing 80mm fan location in the middle. Sounds Complicated.

Side panel, agreed... Now I just need to buy or get a drill ehhh.

I guess I have a pretty good directions on what to do.
But, I wish I could just return this case, I bought from geeks.com for $80 bucks. But, don't think they are going to take it back, loose more money on restocking fees and shipping.

As for the Heatsink, I want to try to solve case airflow first, then decide about the heatsink.


Thanks again.
 
Update,

1st: I've drilled the holes (wasn't easy) in the front panels and created 3 rectangles (open area). it only helped to keep my comp at idle 1C cooler for about 30 minutes than usual.
(I wish I'd knew better, than I wouldn't even touch it)

2nd: I've drilled 80 5/16" holes, right above the Heatsink and CPU. Then I made a duct, and glued it around 80 holes and extended it right over Heatsink FAN. This has helped to cool down motherboard by 3C on idle, and processor by another 5C or so.

Right now my CPU temperature is 41C on idle (opposed to 46C)
Motherboard temp 39-40 on idle, (opposed to 42).

Much better. CPU still runs hot though.

Next, I will look into drilling or cutting back panel, to see if I can fit 2 80mm exhaust fans.

Maybe buy SI-120 a little later as suggested by sumyungai.

Btw, which fan is better to buy? Suggested low speed Panasonic or Medium speed?
Is medium Speed noisy?

Thanks all!
