86C too hot for SandyBridge?

[mmaestro]

I think it has a lot to do with the variety of temperature reading programs out there and the lack of accuracy in their implementations.

There is a solid 10C difference between the temps reported for my 2600K between CoreTemp and the Mobo BIOS readings as reported through Asus AI Suite 2.

I'm inclined to believe the Asus probe results only because they built the hardware and the software, if anyone in that loop ought to be capable of correctly reporting the CPU temps it would be the Asus program.

This is interesting. When I first got my board, an Asus P8P67 Pro, it was running BIOS version 1502 from mid march. At that time, the readings I got for CPU temperature matched up perfectly with what I was getting from the hottest core looking at speccy. I upgraded the BIOS to version 1704 from June and the reported temperatures dropped some 10 degrees - Speccy stayed the same (and somewhere in there I started using HW Monitor instead, it just seems to have more info, although much of it TBH seems inaccurate). Pulling up all 3, with my current idle state I'm getting from AI Suite II 24C, Speccy 32C low 34C high, HWMonitor 31C low 35C high. enough discrepancy that it leaves me basically wondering WTF? I know that the load temperatures I've been pulling from HWMonitor are about 10C higher than what I get from AI Suite II. I kind of assumed somewhere in the BIOS upgrade what the BIOS reports to AI Suite changed from the highest core temp to CPUTIN, which would adequately explain the discrepancy. But that's just an assumption. It rather makes me question which temperature I should be looking at at all.

Use 1/2 a grain of rice right in the middle of the CPU and leave it there (don't spread it). Put the heat sink on. That's it

Wow are you serious? Do you own a 212? I don't know what kind of rice you are eating but it must be grown in texas... There is no way on earth a rice size bit of paste can work with the bottom of a 212 properly. This does work with regular smooth bottom coolers sometimes but NOT the 212. For laughs I went to look up their own instructions on their webpage. They tell people to "spread" cpu paste on the whole surface of the cpu itself. This will work in some fashion but it's def. not going to run as cool as if you spackle up the heatpipe cracks lol

OP's using a Sonata IV. IIRC that only has a single 120mm tricool in the back plus whatever air the PSU moves. However, pulling the side off the case didn't make a difference. I don't think that accounts for the temperature's being quite so high, although (having just checked AT's review of the Sonata) it looks like 80 or a little more wouldn't be out of the question. He hasn't given temperatures at stock yet. I'd love to know what temperatures he reaches without overclocking.

I agree with this. I'm running a 212+ in an antec 300 with a side fan installed (4 fans total) and I can get 60C at stock speeds.

What version of intel burn test were you using guys?I just figured out why my temps were 8-10c higher on linx than intel burn test,it depends on the verison.

version 2.51 makes my water cooled 2500k hit 84c and 2.50 never goes over 74c its also 136 watts vs 103 watts @ 4.9 ghz

I can only imagine how hot that little stock heat sink would get running 2.51.

IM going to set my chip to run 3.7 and stock vcore to see how hot it gets water cooled

EDIT version 2.51 loads the hell out of the cpu,I set my 2500k at 3.7ghz(stock turbo)and vcore was 1.192-1.216 testing and it was pulling 102 watts and hitting 60c on my setup,on air this would easily be 20c higher and on stock heatsink would most def hit Tmax

version 2.50 same exact settings pulls 74 watts and never hit over 53c

You need Ver 2.51 and Win7 SP1...then the chip will use AVX and your temps should get a bit of a boost. (your gflops should nearly double as well)

For 2600K owners, manually select 4 threads instead of the default 8, even if you still have HT enabled in the BIOS, and your Gflops will be higher and your max temps will also be higher despite only having 4 threads loaded on the chip. (this is obviously not a concern for the 2500K owners)

Yup they pretty much doubled and I never really noticed this becasue I would just test for stability on a plain os and then once done I would use my normal os with all the updates and everything.

Here is the problem though,using 2.51 and avx the chip goes over its tdp and there is no way a stock cooler can keep this chip from hitting tmax.

anyone with a stock cooler want to give it a shot,no way im taking my water setup apart again lol.

I have a 212+ with a 2500k and that's exactly the method I use; on all my coolers. You spread a thin film over the whole bottom and you'll do more insulating than you will conducting. My temps at 4.5k are 69-71C at 100% load after several hours. I've tested many coolers both ways and this approach beats-on the "spread film over whole base" approach. To each his own.

I'm running a 2600k @4.4 w/ 1.28 volts, using a H70 in push pull and I get 79c using IBT. Prime 95 only gets up to 71c. Ambient temp is 73c.

FWIW, on my old rig, I went from a 212+ to a H70 and it only dropped 5c. It was considerably quieter,though.

I'm using scythe GT14 fans.

Surely you mean 73F.

Yeah these Corsair H2O coolers don't seem all that great.

Have a H100 here, stock clocks (which is 3.8GHz turboed across all cores) and voltage on my 2600K results in peak IBT temps in the mid 60's. (2fans only though, push config).

I expected much better "out of the box" performance for a $120 cooler.

 

[mhgsx]

Oh, sorry. Ambient is 23.3C (thermostat set to 74F)

When I read about all the temps people are getting, most are missing ambient temps. Without that, there's no way to calculate the Delta between room temp and CPU temps.

So my delta using the H70 with Scythe GT14 push/GT13 pull was about 59C. Using Scythe GT29 push/GT13 pull was 51C. (but way too loud for my tastes). And currently using a Silenx extrema 14 push/GT14 pull with a 7mm gasket between the push fan and rad, the delta is 56C. (still too loud for my tastes, but a hell of lot better than the GT29)

I have GT15's coming in, and I'll test them in push/pull and post up the temp results.

unless I am crazy, stock 2600k would turbo to 3.8 for ONE core.

 

[mhgsx]

We're using the same MB, an Asus Maximus IV Gene-Z. For some reason, it defaults to max turbo across all cores, not just one. It also defaults to a steady vcore, so there's no throttling up or down depending upon CPU speed.

 

[toyota]

I have the opposite going on for me. I actually set all four of my cores to turbo to 3.7 yet when testing it I see fluctuating speeds of 3.4, 3.5, 3.6 and 3.7.

 

[OVerLoRDI]

Not bad not bad, do you have a waterblock on your vidcard too? My 6970 is hideously loud (and i have to run the fan high to oc it to 950/1450) and I thought about getting a block for it.

I run both my cards at 960, paired with a 3x120mm radiator, almost halved the temps and is near silent. Cards run about 50C in furmark. If you have the cash and the noise bothers you, get that thing wet

That was the impression I got from the H70. When I saw the design of the H100, I thought it had potential to be a really solid CPU cooler. I'm sorry to see it doesn't quite deliver what people were hoping for.

Based on what? Forum rumors? All of the corsair products are good products, I use their lower end H50 and my 2500k at 4.6 (+ change) doesn't pass 62c in prime95. If you look at non subjective data form various web reviews, the H100 does exactly whats its intended to do: be a great cpu cooler with a small footprint - from the web reviews and temp tests i've seen, It performs pretty much equally to the NH-D14, and outperforms it in some tests. As far as the mixed feelings above, I don't know. Like all coolers it has to be mounted and configured properly, and ideally it should be in a push pull configuration for best performance. Its not a true water cooler with a water block so its not meant to vastly outperform the best air coolers...it does however perform as well as the best air coolers while having far less chassis footprint. If you want a setup that completely trounces any air cooler you'll have to get a true liquid cooling setup with a water block.....H100 obviously isn't that. Saying the H100 isn't a solid cpu cooler is just lunacy.

Back to my original question for starting this thread.

I checked the temperature at stock speed with Intel Burn Test running at maximum.

The highest core temperature was 61C from HwInfo64. That's HOT!!! Crappy CoolMaster Hyper212+ cooler.

 

[toyota]

61C for IBT is pretty darn good for a 2600k. try that on the stock cooler and I bet you easily hit 80C or more. and if you go play some games with stock speeds and I bet you only get in the mid 40s.

Well, since many members here , myself included, have found the the 212 to do an adequate job with substantial overclocks - 4.5 -5.g - it would seem there is something besides the cooler contributing to your problem ...
