Sure, bro thumb.gif I said you make no sense because I don't get what you're trying to say. Maybe you don't speak english well, which is fine, but my comment meant that your post made no sense in reply to my post, which you quoted.

Anyway, do you water cool (Antec Kuhler doesn't count, sorry)? Seems to me you're going off about something you know nothing about...?

No, i dont know nothing about custom watercooling.... I prefer the most economical way to achieve something XD..

But im not blind either and know how to read and how to look for information when needed..

If this
HW64temps.jpg

Is not enough, then what is enough??

I can run furmark @ 40c? Oh wow.... lmao..
What furmark does for you? Nothing XD..


Like i said, this is overclock.net where people put their hardware below 0 to do a 10 second suicidal run...

Yes it will level out but by running loop in parallel before the radiator hitting 2 blocks separately the liquid isn't going from one hot block to another block like it would happen in series.


The over all temperature in the loop will level out based on how good of fans and radiators are able to cool.


Once I get my custom vrm block made up I will post some testing results so we can all see how it performs. IF the water block on the VRM doesn't show any performance increase then I will just stick with air heat sinks on vrm and vram.

I will stay tuned, please do a regular (REAL CASE SCENARIO) like the game test... Theres some people that really dont care about unrealistic payloads like furmark....

40C VRM is amazing, especially on air, but again you can see that they aren't under a lot of load, and therefore not putting out a lot of power. And actually, those are his temps in game, not in Furmark. I suspect Furmark would cause the VRM temps to shoot up to 90C like he showed in post #55.

Well, we can agree to disagree smile.gif

Scratch that... I told you stick to aida lol...

Why you worry about getting the thing loaded in furmark?? Real case scenario is not furmark/prime or ibt....
I use them dont get me wrong, but i use them as a tool to measure my system stability and cooling options.. Other than that is worthless in a real case scenario..

Real case scenario is checking temps while you are playing for example, or checking temps while you are working or checking temps when playing in adobe XD....

Not to have an ease of mind of i can run furmark on the vrms @ 40c, i mean come on....

PD: Oh wait XD, hdwinfo to combobulated XD,... new test down 2 posts XD
Still over 40c tho XD

The HWifno32 was buggy. Sensors were not reading properly. Tried HWinfo64 and the temps look much better. HWinf64 supports more video cards. About 15c lower with HWinfo64.

Might want to mind what you say about FC blocks as well... seems to me Swiftech found them valuable enough to start producing some smile.gif

If the VRM's operate on factory specs, then the board operates on factory specs. VR's that are "acting-up" as you say are either defective, or operating beyond specs, so using this as an argument to illustrate your point is not relevant to the point I am making.

"Feeling comfortable" as you put it is a purely subjective matter and has no place in practical engineering. While I respect your feelings, they don't change the facts.

If you can demonstrate to me with a convincing example that cooling your VR's bellow their max rated temp has enhanced your overclock/stability, then we'll talk further, I'm all ears. Believe it or not, I'd love to be proven wrong. But to the best of my knowledge, all it practically does is extend the component shelf-life. You will find plenty of stories all over the forums where people are speculating about this, but speculations are not facts. Take a functionning board, put it thru the bench grinder, overclock it to the max, while keeping your VR below their max temp, and find me the example where running at 100C makes any functional difference compared to running at 50. If you do, then I will concede.

As to making FC blocks ourselves, I clearly said that both solutions sit side by side with each having their own sets of benefits didn't I? But it doesn't mean that I have to contribute in reinforcing what I see as an urban legend.

Plenty of us here want to cool VRM and VRAM just because we can. This is overclock.net, after all. Calling it dumb is, well... dumb. Some of us simply don't want our VRM or VRAM at 80 or 100 or 120C, and there is nothing wrong with that, even if the silicon can handle it anyway.

As I've said before, gpu only fine if that's your thing but it comes at the cost of not cooling your vrms any better than stock in essence. You've got a problem with that?
Take the OP's setup, he rallies on and on about the gpu only block, only to add a vrm block, thereby defeating the very point of the gpu only because he adds further heat and restriction. Folly is not?


You are right, and I am sorry if I offended anyone by using the word dumb, it wasn't diplomatic on my part; on the other hand read exactly what I said: "..low temps just for ther sake of bragging is not a practical purpose."

I am the type of person who wants actual tangible results and sometimes I get irritated by the bling aspect of things. I shouldn't. It is after all part of the fun, thus part of the motivation. But I do want people to understand what it is they are doing, and why exactly they are doing it. If you tell me "I like to get low temps just because I enjoy the challenge", then it is something I can understand and appreciate, but when people start justifying their actions with incorrect technical data, it contributes into spreading false information, and I believe that it is my duty to explain what I know. [Edit] and if I am proven wrong, then so be it . That's how we learn isn't it?
