Re: Replacing Stock AMD Processor Fan
 

Yes indeed, though if the cooling solution can handle all cores at full load then it'll have no problems handling any individual core either. Also I tend to find second-to-second variation to be much bigger than per core variation, for example my temps can drop or increase by as much as 10'c over two seconds but I rarely see more than 5'c delta between cores.

Re: Replacing Stock AMD Processor Fan
 

I noticed this weekend that my temps were a little higher than usual even with a stupidly big radiator on my cpu and motherboard.

The good thing about the radiator though is that the fans that are on it are only running at 1200rpm, and my cpu core temps went up to 65c and that was with a ambient room temp of 28c and 100% cpu usage whilst, converting 30 videos.

Idle temps were running about 35c to 40c.

Hopefully Intel Haswell E when released will run abit cooler than Sandybridge E but, with it being a 8 Core cpu it might be around the same temps.

Ah yes the cortina one - it was an impressive sight at the LAN :)

Re: Replacing Stock AMD Processor Fan
 

It was funny seeing some poeples reactions to it :D

It's not the biggest that I could have got though, but I am probably gonna go back to air cooling for my next build.

Re: Replacing Stock AMD Processor Fan
 

Seriously? I think there's something pretty wrong with that setup if those are the temperatures you are getting. I've seen better heat dissipation on a 240x120mm radiator with 900RPM fans.

Hell, my single-fan air-cooler at 1100RPM does better than that... Double-hell, even my SFF (2cm high) Intel stock cooler keeps the core temp to around 65'c under load, albeit on a Haswell Xeon that probably consumes less than half the power of your (and mine) overclocked i7's.


For the record Haswell thus far hasn't turned out to be any less power hungry than Sandy or Ivy Bridge under load (sometimes even a bit higher) but is a hell of a lot more efficient at idle and produces better IPC. I wouldn't expect that equation to change much with Haswell-E.

Re: Replacing Stock AMD Processor Fan
 

I clearly stated that i have a AMD 1035t and as you know this chip runs nice and cool. Yes even with the stock cooler.

And and for you saying that one can not achieve a cpu temp lower than the ambient room temp. Of course you can. A good air cooling set up can do this effortlessly unless you happen to be in a room where the temp is unusually high, like a server room without air conditioning or you live above Satan and he's got his central heating on at max due to having a nasty does of the flu.

my case has very good airflow with a 120mm intake and two 80mm fans at the top rear drawing all that cool air over the cpu and exhausting it out the back. Now you said that the numbers i stated have no resemblance to reality. Think about it, why would i do this with such a medium spec machine like i have. Don't you think i would have also lied about my machine specs as well. perhaps adding a top end cpu and a graphics card that runs hotter then hell ?

To be blunt, you come across as a bit of a arrogant git. Perhaps in future you might want to choose your words a little more carefully before basically accusing people of lying.

Re: Replacing Stock AMD Processor Fan
 

Umm, no. This is absolutely impossible. One of the fundamental basics of cooling and physics. Since you don't seem to understand this, it seems obvious why the rest of what you've said is also total rubbish.

Note 57F is 14'c and 70F is 21'c room temp (an average to warm room). Pretty much the exact same BS you're claiming.
Need I go on?

To be blunt, you are lying. The fact that you think you're right while you have absolutely no clue what you're talking about, and are adamant you are achieving the impossible in the face of overwhelming evidence proves you're the arrogant git.

Perhaps in future you might want to check your facts before making claims that are impossible then accusing other people of being arrogant when called out on your lies.

This chip I have is not a very good overclocker, it needs 1.45v to hit 4.6ghz for full stability but if I want it stable enough to just game on then it will do it at 1.35v and hit temps of about 50c.

Sandybridge E chips are hot though, which is why many air coolers don't work on them even at stock speed and the likes of Corsair's AIO's don't do a great job on them.

That radiator though may be large but it doesn't drop the temps by that much although, it did drop them by 15c when going from a 480 and a 360 to the 1080.

It is currently 26c in my room and my cpu's core temps are ranging from 39c to 45c, and if I was to take the overclock off they would drop down to atleast low 30s.

Re: Replacing Stock AMD Processor Fan
 

Ah OK, that sounds more like a reasonable range. Was it Sandy Bridge (or was it Ivy Bridge) that Intel introduced the dodgy IHS compounds that made it run hotter?

I'm just comparing based on TDP, my 1st-gen i7 is rated at 130w TDP at stock, as is your 3rd-gen i7 3930k. Mine's not really stable above 4Ghz at all, at least not on air cooling, but at 3.8Ghz - 35% overclock above stock turbo, it gets to about 65'c core on air. Yours is only a 21% overclock above max turbo but still nearly a Ghz higher than mine. It's hard to say which would be taking more power, mine's got a bigger overclock but yours is running faster overall and on higher voltage, yet mine's on older, bigger process (45nm) so yours is a lot more efficient.

Low to mid-30's under load is pretty decent, 45'c is OK I guess - depending on waterblock and IHS performance. It's the 65'c you mentioned earlier that seemed a lot higher than it should be, given my CPU does that on a standard air cooling. Not harmful by any means, but when you consider the tiny cooler on the right of this image keeps a 3.4Ghz Xeon Quad to under 65'c load, two of them together would give comparable performance to your hex-core at 4.6 and have a cooling solution a tenth the size seems a bit odd.

Re: Replacing Stock AMD Processor Fan
 

My temps are always high because of the ambient temp of my room, as it has direct sunlight all day and my brother put, a shed load of insulation in the attic.

My normal ambient temp in my room from March to October is anywhere between 24c to 30c, and from October to March it sits around 16c ambient and that is when I do allot of benching because of the lower temps.

Still I am tempted with a waterchiller but I really cannot bothered with insulating the board to reduce the risk of condensation.
