At idle im getting these temps. 48c 48c 48c 45c

It passed a standard Intel Stress Test. Temps went up to 82c 82c 80c 79c

I did a blend test in prime and the temps went up to 84c 83c 82c 81c

Im thinking these temps are slightly too high?
But its still 16c before it resets and at least im not getting the blue screens I was getting before.

I think tomorrow I will swap round the fans on the h50 and see if that makes any difference. A few degrees lower would be great. Thanks for reading.

why would you want to be pulling warm air through the rad?

The top fans will probably be extracting it pretty quickly so i doubt it will be adding much to the overall case temp.
Click to expand...

the reason you have fans blowing through the case all in one dirction is to have some thing called positive air preasure (thats why you have more bigger fans blowing in and less smaller fans blowing out) and to speed the air flow throught the case as other wise it will just be blowing it all in keeping what hot air is about inside the case, you want a clean air flow from bottem right going through the top right (looking from the same angle as your pic) as heat rises and the coldest air will reach the hotest componat 1st the GFX card then up past the cpu and out

ps sorry if my spelling is bad ive just had 2 litres of wine lol misses is a light weight lol
 
In the guide i used it had 3 speeds, 3.36GHz, 3.8GHz and 3.99GHz.

At speeds 3.36GHz and 3.8GHz the QPI/Dram is set to auto and at 3.99GHz its set to 1.3v. I was just putting the settings into TurboV and it doesn't let me set it to auto. Would it be ok to leave it at 1.3v for all 3 speeds?

edit: When its set to auto for 3.36 and 3.8 in the bios, it shows up as 1.375v in turboV.

Manually set the Qpi/dram to 1.3v rebel. You really should'nt need more then that for 4ghz or lower.

For lower speeds you could even lower it, but you would need to test for that though.

Remember those guides are just that, a guide each cpu will be different, you will still need to test a lot, I notice in it they are at 1.25v for the cpu, i bet that would fall over under F@H lol.

But yeh Qpi manually set, vcore manually set, ram manually set, rest can be on auto.

Also once you have tested the settings whilst using turboV u can save the profile and load it up into the bios using OC profile. Not tried it myself, as i generally just enter the stuff myself, save the profile and done, but im sure u will be able to save a profile with turboV and do it the same way.

But generally i try and remember what they where, or write them down and enter them myself, that way u get to know the bios a lot better.
 
As the 4.00GHz speeds were pushing the temps the wrong side of 80c I have settled on a 3.8GHz clock for now.

BCLK 181
Dram 1451
Cpu 1.2
Qpi/Dram 1.3
Dram bus voltage 1.64

Max temps with these settings are around 78c under load. I have been taking notes as I go so I can always use them to change the settings in the bios, I just wanted to know about the turboV because I also have the OC Palm thingy.

If these settings look wrong please let me know. Thanks.
 
Don't forget to stress test for long periods, nice low vcore for that, might be able to lower the qpi some also, which will help the heat.

I have to have 1.3v on my qpi, anything lower and i'll get random BSOD's when folding, but never when using stress testing lol.

But also if u don't encode, or use something like F@H no game will reach those temps, so nothing to worry about really.
 
Yeah I've been doing intelburn and blend tests. I'm just going see what the temps are like in GTA4.

I will try lowering the qpi a bit next, would be nice if the temps come down a few degrees.
 
Lowering the qpi dram below 1.3v made the system very sluggish, it took over 5 mins to load. I'm going to leave it at 1.3v for now.

Playing gta4 the temps didn't go over 61c.
 
If Gaming is the most intensive thing your comp will do, then those temps are more then fine, what you have to remember is yes prime/ibt/linx can really heat up the cpu, but u have to really go by what the max your comp is likely to do from day to day.

So 61c is fine and nothing to worry about.

For example i do F@H which is very cpu intensive and heats it up just like any stress test. Thats why i use custom water, so i can keep it below 70c across the board, even on the hottest summer day.

So its all about what your comp will be doing, if u will never reach stress test temps doing normal things, then don't worry, yes its nice to have low stress test temps sure, but if your comp will never do that much day to day then don't worry.
 
The viper fans are meant to be 1900rpm but mine never go above 1400rpm. I have them connected to the PWM splitter which is plugged into the cpu fan slot on the motherboard. Am I doing something wrong? I have tried changing settings in AI Suite and they never go above 1383rpm.

edit: Also I have an optional fan that it says only use if you are using a passive cooler or a water cooler. Is the H50 considered a conventional water cooler?

No, no need to use it, come to think of it there wasnt even one supplied with my p6t deluxe v2. Regarding your viper fans not speeding up, make sure that cpu qfan is enabled in the bios, (hardware monitoring section), then select from the profiles, eg silent, standard, turbo. I have turbo selected on mine, in windows using asus ai suite open fan expert, select a profile that matches bios setting then calibrate the fans and apply, no matter what profile you select, as a failsafe the fan should run full speed if cpu temp gets to high.
