Ambient temperature regarding H100?

Hey guys,

I'm a huge Linus fan! I've only recently got involved with the forums sadly but I'm loving it already! Even though VB5 is a little.. *cough* >.>

Right basically I'm looking for some solid information regarding ambient temperature and the Corsair H100. I've always known/thought that air cooling that doesn't include any external form of cooling that itself is below room temperature such as in-drawing outside air or using liquid nitrogen etc that it's impossible for a fan to cool below the air it's blowing.

My friend who's been building PCs since well before my time assures me that he can get his H100 as low as 12c whilst his room temperature is around 20c? He proved the temperature reading to my other friend confirming this. I also know that the lower the temperature the less stable the temperatures can be.

Any information will be greatly appreciated. :)

Best regards

Technically... if you throw enough fans at it, the air flow through will continue to cool even below ambient and sub zero.

This was a bit of a troll by Tom over at TTL - but you get the idea -

He put 40 fans on his H100 and was able to get sub zero temps. So, the better the fans, and the more of them, the better the temps. Also note, these are static pressure fans, not air flow fans, which generate a lot of pressure and can cool better then you would think.

Wait what? TTL put in an offset in coretemp of like -40C to make it appear as if it was below 0C, i could make my H80 seem as if it cooled my cpu to -179C but it wont really be the case.

As for your friend, does he happen to have an amd 1090T or something along those lines? Because ive a 1090T and with coretemp or something it will show a temp of -8C of what it really is, they have a bug which makes them report a lower CPU temp than what it actually is

Hey there. You are looking mighty fine today, have my virtual cookie!  :ph34r:

Where did you see the info about an offset??

Thanks for that - I never read any of the comments on that. I knew he couldn't be hitting -'s, as there is no frost or condensation, but I would have though with all the pressure, would be very cool. Did you happen to notice in the thread if they mention the real temps?

Ah so that 40 SP120 mod actually didn't influence the temperature hardly, It was a troll video? So no matter how many fans you put together, they cannot go below ambient?

Sorry if I missed something. :)

Physics dictates that unless you're doing something like LN2 or Phase Change for your cooling, you cannot have temps lower than ambient. It's physically impossible.

I know that if you have an amd chip, the core temp is figured through a calculation that on balances out at about 30c to 40c.

You can find this in the amd forums.

Like with my 8350, my ambient can be 25c with h100i liquid temp at 30c but my core reads 14c

Only under load does the temp become accurate, that is with amd chips, idk about intel.

Yes, sorry - that was a bit of fun about he 40 fan project. :) Also, depending on what monitoring software you use, it itself may be buggy and not showing the right temps...

This.

Either your friends temperature measurement is broken or he is simply trolling you.

A H100i is a decent cooler, but there is no way you will get temperatures below your ambient.

So either he's doing something wrong or he is trolling you hard ^^

[Had a similar Software bug yesterday when I re-setup my computer -> CPU-Z was still installed on my 2nd SSD and when I ran it it showed me a BCKL of 400 ^^]

Important if he has an AMD chip!

"Core Temp" is what AMD refers to as "TCTL" and is a non-physical temperature on an arbitrary scale measured in degrees. It does not represent an actual physical temperature like die or case temperature.

AMD designed this equation to accurately read peak (45C+) and load temps. It has an equational offset to determine said temps which equalizes at 45C. Since it's designed for peak temps and is a non-physical temperature it cannot read idle temps or account for ambient temps correctly.

so if it is an AMD chip, nothing is wrong
