15C is very low. What kind of fan are you using?

This one: http://www.newegg.com/Product/Product.aspx?Item=N82E16835103031

And I should have prefaced those figures with the fact that the ambient temp in my house is about 65F right now. I keep my house cool during the winter.

Nevertheless, more than a 10C drop in temps is still incredible. I'm loving the new proc.

Edit: Half the pic got cut off, so here's the rest:

Very nice. I would buy your old CPU, but I got a cheaper version and overclocked it to 2.2GHz, so it wouldn't really be worth it :)

I have a 4000+ in my HTPC. If it was more than a marginal upgrade, I'd buy the processor from you, but I don't think it would be worth pulling my HTPC out of the closet.

I've never used Speedfan before, but I think you're reading it incorrectly. I don't think the 15c is the actual CPU temp. A normal fan couldn't lower a CPU temp to 15c. Unless your running the computer outside or in a cold environment.

@jayWHY: Yeah, the metal is probably a bit hotter than 15C.

But, he is seeing a 10C drop using the same measuring device. 10C is a lot of overclocking room, which is what he's stoked about.

I bought an Intel Dual Core E2160 chip clocked at 1.6 Ghz from Newegg and overclocked it to 3.0 Ghz on my stock fan. It never runs over 50c either. If anyone else is in the market for a new chip I got it for around $70 on Newegg over Christmas.

Heres the rest of my specs if you were wondering....

2 GB Gskill RAM at 800mhz (underclocked to 788 so the chip could run up to 3.0 Ghz)
Gigabyte Intel P35 mobo
Nvidia 8600GT

@ jayWhy/rapture, when I first dwnlded Speedfan, I wasn't sure exactly how to read it, either. But, seeing how the monitoring program that came w/ my motherboard (PC Probe 2 from Asus) consistently reports the exact same temps as Speedfan for CPU, both during idle and load (they must be reading from the same monitoring chip). Playing games or rendering video makes them both rise at the same time, exact same temps. Both readouts also drop at the same time. They even hover at the same figures. You get the point.

For the purposes of OC'ing, I have used them both, but speedfan loads faster, and doesn't have the annoying look of PC Probe. So I use it more often. Just for sh*ts and giggles, I included both temps in the screenshot below.

If you guys know of a better temp monitoring program, let me know. It'd be worth the time to dwnld a 3rd one just to compare.

But, like I said before, I keep my house in the mid to lower 60s during the winter. A summertime ambient temp of 70F would no doubt yield different results.

A modest 10% overclock to 3.0GHz yields the following:

You may need to click on the picture above to see the whole thing. Due to narrow margin restrictions on this page, it cuts out about a quarter of the right side of the images I'm linking to on flickr.

@D15AV0W3D: I'm measuring my temps through a thermocouple that's sitting on my CPU between my watercooling block. I haven't ever checked that temp versus the temps in my BIOS or from software. I'll try to do that.

That 15C is really low - especially reading the NewEgg reviews for your fan. Most everyone's starting out in the mid-20's and then going up into the mid-30's (or higher) after an OC (which is within the range that your old chip was in). Those people were probably running a 90nm chip.

I'm now guessing that mid-teens C is about right.

15C is 59F. It is impossible to have a CPU be lower than the ambient room temperature unless your using some sort of condenser. A normal fan will not do this.

Maybe the software detects the lower voltage on the chip, but is calculating the voltage as if it were at 90nm chip.

I originally thought the temp being reported was strange, too. I know that 20C is roughly 70F. So 15C seemed a little on the low side. However, that's what both Speedfan and PC Probe were reporting. I'm not fabricating these #s. I don't have a thermometer in my game room upstairs, and don't run the heat very much up there. So the more likely scenario is that it was cooler than 59F in my game room that day.

When I was into RC vehicles I took a digital cooking thermometer, stripped off the metal probe, and secured the thermocouple to the head of my engine to act as a temp gauge. It was about $10 IIRC. Perhaps that would be a good solution to get a "no shit" temperature, regardless of 65nm/90nm voltages or software.

What's the temp you're interested in? Chip? Heat sink? Ambient in the case?

Surely it was not colder than 59F inside your house that day. I'm thinking it would need to be something like 50F ambient to get that reading from a heat producing source like a PC.

hey i have a AMD Anthon Dual Core x2 3600+ and The Temp Runs 13C and 55F is that good or bad??

but im getting a AMD Anthon Dual Core x2 5400+ 2.8GHZ a Geforce 8600GT 2GB g.Skill Ram at 667MHZ Pc5300,Ultra 400Watt PSU and OCZ Vanquisher Fan/Heatsink.

But is 13C and 55F for a Stock Comp just bought a good temp??

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01063553&lc=en&cc=us&dlc=en&product=3443509&lang=en Thats The Motherboard and Comp i bought for 248 just incase u all wanna know

I've thought about this some more and I am banging my head against the keyboard because I didn't think this through. WTF Engineering Degree?

The fan is a mover and it can cool something to below ambient room temperature. It's a matter of convection. You pump enough air across a surface and it will eventually carry away the heat.

Cooling a CPU to 55F is certainly possible with modern fans - even stock fans.

I totally believe the numbers reported in this thread.

I was hung up on passive cooling techniques which has thrown me off and had me believing the numbers were too low.

It's good to have some valid reasoning behind the temps. The whole thing makes more sense to me now. I was beginning to doubt the numbers myself, which didn't make sense, b/c the two programs have both been proven to be reliable. I just didn't entirely understand the concept behind active cooling, nor convection in this application.

But, what you said makes sense, esp. since the fan isn't blowing down on the proc, but rather across 25 or 30 aluminum fins, which are parallel to the proc, and attached to the 3 copper heatpipes that run through them all, and are connected to the copper heatsink. The fan is positioned such that it is almost perfectly aligned with the exhaust fan, so the warm air is blown directly out of the case.

Just finished up the hardware build on my new rig, q6600 on a P5E from Asus, 4GB ddr2 800 gskill, sapphire 3850, 4x400gb 1x750gb, cooler master cosmos 1000. I would have waited for the e8400 or the q9xxx series, but I needed this now for video editing. Mmmm tax deductible computer parts :).

DJ

Wow, DJ. That's a killer rig. So, do you have the Orange Box yet?

Thanks to the many, many others I've run across who have Brisbane chips (the one I have) and who are getting mid teens C temps (stock speeds), I'm now completely confident in my readouts. Mid teens C is not only possible, but expected out of these if your room is at or below 70F, you've got a decent after-market hs/f, a case w/ good air-flow, and haven't OC'd it yet.

Nice rig, man. It must have cost you a pretty penny. Good thing it's tax-deductible!

Actually, everything combined came out under about $1500 with rebates and all :). The 400gb drives I've had for a couple years now, so they're not part of the cost :).

DJ

Had Orange Box for a while now, for PC, just haven't installed it. Been waiting to build this computer before installing it.

DJ

...if you can itemize more than the standard deduction. I have yet to be able to crack it.

I'll break it :).
