Temp check for new i3770/GTX670 loop

post #1 of 3
Thread Starter 
I finished a new build last night using an i3770 (non-k) and EVGA GTX 670 FTW. Here is a bad pic:

Loop: bay res w/MCP655 > RX120 > Heatkiller 680 block > RX120 > XSPC Raystorm > EX120

Fans are Gentle Typhoons running at 800RPM, 655 is running at 1.5 setting (going for silence).
CPU TIM is MX2.

Now, what bothers me is my temps, @ 25C ambient:

Idle: 35C CPU/31C GPU
Load (Prime95 for 20 mins): 55 CPU/38 GPU
Load (BF3 for an hour): 45 CPU/45 GPU

I'm ok with the load temps (especially since Ivy runs hot because Intel is cheap) but why is my i3770 idling 10C above ambient when the entire system is outputting no more than 100W?

I've taken apart the entire loop, flushed all rads, opened every block and checked for particles (the Raystorm was put back together correctly), checked to make sure I'm using the right inlet on the Raystorm, reseated it and reapplied TIM, but I get the exact same temps. In fact when I had this set-up with just 2 x RX120, the temps were pretty much the same. I feel like 3 rads should be able to keep an idle, down-clocked Ivy at no more than 2~3C above ambient.

My guesses are:

1. Raystorm is bowed, so there's still crap contact with the Ivy heatspreader no matter how much I tighten the screws
2. The combination of low flow setting, fans at 800 RPMS, and drawing hot air from inside the case (using the rad fans as exhausts) is causing this. However I've tried the pump on 5 and fans at 1400, the idle temps went down to 33/30. Opening the case also brings down temps to 31-32, but still not 25.

Any ideas?

To be honest mate, ambients don't matter in the slightest, your on load temps are absolutely fine, the only way you'll get them down further is if you set your vcore.

I have to ask, why didn't you get a K model?

Ah, thanks... yeah I guess I am nitpicking, read too much into the "if your loop is over 10C delta you're an idiot" thing.

For some reason I wanted to save $50 (it was on sale vs. the k model at the time). Looking back, I don't know why I decided to save $50 and then spend $200 on an overclocking motherboard and $600 on WC. I guess I'm kinda past the whole overclocking thing though, this thing boosts to 3.9 anyway. Overclocking used to bring noticeable performance games in work/games for me, now I feel like it's mostly a fun way to waste time.
