SLI/CPU heat issue 670 ftw - Page 2

Adding another card really creates such a drastic change?

Anyways when I had the accelero twin turbo installed I ran that and I thought it was alright, but the temperature actually kept increasing as the burn-in test continued to the point it was doing 90C at 1.250 so I thought it was because the hot air was circulating into the case not out. These results refute that idea somewhat, I still get absurd temps with SLI.

The block is definitely on the cpu, I've no idea what to make of this situation. I tried reversing the top fan to intake as suggested and got NO EFFECT still 80C full load. How can this BE?

I ran full load at 1.1 core volts and full load on the GPU it was max still of 80C, so this tells me the temps are stable but the CPU temp makes NO SENSE. How can I have such a huge drop in overclocking ability?

Anyways I will do more testing but this is totally ridiculous IMO.


Your fans are not doing the job, Period. Your cable management is restricting all your airflow needed to help cool your system down. I would re-route all those cables and get better fans.

Also when you do add an additional card, even though it may be a blower type, the GPU Still dumps a ton of heat into the system. The blower does an adequate job in cooling it down. there is still a ton of heat getting dumped into the system...



In the end, you need some better fans.

The thing is there's a bottom intake that pulls air directly upward to the bottom SLI card, yet it still gets 70-75C, it's absurd. And then there's my side fan that intakes air which again should cool these GPU's down more and the CPU. I ordered a 140mm side fan to replace my 120mm and will increase it's voltage to 10 volts when I get it. But yea this confuses me, and the desk doesn't allow me to put a fan like that frown.gif it's inside the desk area.

What I might try is turning all fans to 12 volts, then burn in testing to see what the results are, though it's pretty goofy. Anyways I'll post again later

more like FTL I guess?

I'm quite perplexed here but I also give up. Watercooling is the way to go in the future for me, not all-in-one either. I will begin saving for the future.

My final results which I can live with are:

3770k (delidded) 1.1 core voltage @ 84C full load (with SLI full load) or 80C full load (without SLI on full load)

and

The SLI results which SUCK

Top SLI 80C full load 30 mins (at 80% fan speed)
Bottom SLI 77C full load 30 mins (at 80% fan speed)

I changed the 2 front intakes to 8 volts, the bottom intake to 10 volts, the side intake 140mm fan I found to 10 volts, the 2 top 140mm fans are connected to the motherboard and can be set to whatever RPM I want.

The H80i is setup with corsair link.

I"ll maybe get some nylon washers and try that since there was a gap but I have checked and this thing is very snug on the CPU I can't move it or anything. I'll report back if I ever figure out a better way to cool this.

PS I turned the fans all on 12 volts at 1300 rpms (120mm ones) and the 140mm ones on full as well, burn-in testing resulted in similar temps. Go figure

Is your case inside the desk, that box I see in the picture? Does it have room for air to flow out the back?If it is that seems alittle restricted to me .Hope I'm being short sighted. The method from lilcronic works real well. You could try taking it out of the desk cleanup those cables and test.Good luck.biggrin.gif

I found out what the issue seems to have been so I'll just post it here.

First of all the Corsair Link H80i went in the trash, it just didn't cool very well and I got mad.

Secondly, I used Coollaboratory Liquid Pro on the die of the 3770k after I delidded the thing, but it seems that when I removed the NHD14 heatsink somehow it may have moved the ihs, or changed the contact of the ihs and die. After removing the liquid pro, then using a normal thermal paste and reseating the NHD14 my temps are now more normal I can maintain 75C at 1.190 core volts on full load with my SLI running full load. I really believe the contact was messed up somehow on the ihs and die when I moved everything. I'm to lazy to use more liquid pro on it anyways...........

I also added a front 140mm fan in the drive bay which totally impresses me that it even fit / worked lol I'll just get an external bluray writer usb 3.0 later

The mystery is solved
