Hello I have an i7 4770 with box cooler on stock settings, on an ASUS z87-plus, epu enabled, with RAM xmp profile at 1600Mhz enabled, other settings auto (hyperthreading, speedstep, superlfm enabled).
I'm using HWMonitor and prime95:
I have good idle temps (32-35 celcius) for a stock cooler that has been reseated and using intel's pre-applied striped thermal paste (which must really have bad coverage now). I will clean it up these days and try with some AS5 on and see if it makes any difference. I am not looking for a new cooler, thank you, I am not doing constant heavy CPU work right now, but those temperatures do scare me.
In games I get around 64-75 which should be ok, but it should be much lower. I recently tried prime95 64bit in-place large FTTs for 5 minutes and it spiked to 80, quickly raising to 98!!! ("package" is 95, core 0 to 3 are: 96,98,98,90.
This is ridiculous, even for a stress test, it's alarmingly high. TjMax is 105, TCase is 78 I think.
For no overclock that is extrememly high, youl need to take it apart and re apply some cpu compound (whichever brand you prefer) and try it again making sure its seating correctly.
Ive seen a few folks de lidding the chips and sorting out the crappy intel compound they put under it but its hugely risky to do if youve never done it before.
that's actually not really high for stock with a bad stock paste job running in place on prime95, the stock cooler is shit anyway, they've always have, and they haven't inproved the stock cooler at all, and if your CPUs keep getting hotter and hotter and you don't make a Cooler that's better than the last its just going to get really really hot
just like I reccomend with 6300/8350s I recommend a cheap cooler to lower temps and noise levels
I recommend a Loki or Gaia for stock CPUs, never use stock heatsinks on higher end CPUs
This doesn't surprise me. I have a 4770k, it is the hottest CPU I have owned. Obviously, prime95 doesn't deliver anything "real world", but I keep it a very safe OC of 4.2.
At 4.6 I was bang on 80 degrees with a 12DX cooler, too high for me.
You shouldn't stress it under prime95 with only the stock cooler in place.
Why would it not be reccomended? I think it's because it's not testing all of it's potential instruction sets, but that means aida64 would give even higher temps. Again, for normal use I've had much lower temps, but still worrysome (up to 75-76 max in some games or rendering). I'll change the paste soon and update if it's any better.
Because Prime95 is not a real world stress test. It loads down the CPU several times more than what modern CPUs are designed to handle thermally. You are destroying your CPU whether it be an Intel Haswell or an AMD FX-8350 when you overload them with Prime95 for an hour or more degrading their lifespan by as much as 1%.
You have to remember Prime95's base code hasn't changed since the days of the Pentium III and Pentium IV. They may have added support for more and more cores/threads over the years but that doesn't mean the base program was designed for modern processors. Modern processors with 4, 6, and even 8 cores pump out more thermal energy than a single core 3.4 GHz 103w processor that only tips 141w overclocked to 4.06GHz.
AIDA64 systematically tests each instruction set therefore you never see an excessive heatload on the CPU. My FX-8350 hits 66*C on the socket and high 50s with the cores at 4670 MHz on 1.440v during AIDA64's stability test where as within minutes of a Prime95 stress test my CPU socket would skyrocket up to 85*C and cause the system to crash.
The old paste was already dry and cemented, with some gaps.
I just applied some arctic silver 5, in line method, same box cooler. 85-86 celcius using intel extreme tuning utility (same as other reviews). It might drop some more since I was on lowest fan settings and I just applied the paste, I hope with curing it will drop more. It's even better now in normal use.
I guess your right, I mean it didn't throttle at all or report it as a warning temperature (realtemp and intel). On prime95 blend test, I get the same decent(?) results. Still, I had decent temperatures on my old Core 2 Duo on in-place large fft. I'm going to report back if temperatures on full load with a trusted synthetic test drop a little. I would've liked under 70 degrees since I already have a heat factory hd 4870 installed.
Anyone else using a stock cooler on theirs? I am getting 72 in games max now and 32 on idle. I guess this is how the chip's supposed to be like. Any opinions?
Actually the chip is longer than a core 2 duo or a mobile chip so to spread the heat well you need to use the line method for these kind of quad cores.
Pea method is too much depending on your CPU. Grain of rice for AM3+ CPUs, line method for intel CPUs. Pea method might be fine for a LGA2011 but it's way too much for either 1155, 1150, or AM sockets.
Wuh, you don't want a new cooler? Why not? Intel only gives you that cooler so you can make sure the CPU works, you really shouldn't use it other than that.
For the moment, no. In the long run, I'll probably set some money aside this year for a good cooler.
I'm probably falsely alarmed because this is a low electrical power CPU with high temperature rating, which is good, because I can get a more silent cooler than say for a Pentium 4 EE, who topped at 70 degrees.
I'm going to go for a Scythe Mugen 3 or simmilar, in that price range.
for HDT coolers you want to use either 2 or 3 parralell lines on the heat sink depending on if you're using intel (2) or amd (3)
for example on the xigmatek dark Knight II, for an AMD chip you'd want to apply one 1' long line on each of the heat pipes but for intel you'll want to apply 2 lines on the two inner spacers
One really bad thing I did after changing the thermal paste : I scraped the heatsink, thinking it would yield better contact surface. It does the exact opposite.
I recently bought a CM Hyper 212 evo (I always envied and criticizing people with their intel + 212evo builds, being all the same, now look what hypocrisy). In prime95 in place fft same test and time it never goes past 69. I am a really happy user now.
