Fixing my sad i7 920 Water setup

post #1 of 2
Thread Starter 

Hi guys,

I have an i7 920 system on water using some very old swiftec radiators (I think they are from the 8600 water kit, see:

). They are blue and haven't been sold in years, one is a 120mm to which i attached a delta 240cfm fan (yes yes.. i know) and the others are 80mm with slower fans on them, of which I am only using one in my loop (single loop). Lately I've been interested in overclocking but my temps have always seemed a lot higher than other peoples ~40c idle ~70 on prime95. The temps are fine for stock use but they are just high enough that I'm avoiding oc'ing until the temps are under control. My case is also a dinosaur, its an antec dragon mid tower ( http://www.ttecx.de/files/news/newsb...tec_dragon.jpg ).

So here is my question: With my current setup (specs below) would I see a significant temp change by switching to something like a 3x 120 mm radiator or bigger and just putting it outside the case (that's where my current 120mm rad with the delta is because it was too loud). I really don't care about having the tubing go out to an external radiator but i'd like to just buy one really good radiator that will give me some future cooling capability so that I can just set it and forget it. Any recommendations would be welcome. Thanks,


My system:
Mobo: Asus P6T Deluxe
Proc: i7 920 - Stock ~1.25vcore stock speed
Vid: Evga gtx 580 hydro 2 ftw
Ram: corsair 1600 ddr3
HD: single ssd (not really my heat source)

Cooling: 1x 120mm swiftec radiator with delta 240cfm, 1x 80mm swiftec radiator with 80mm ~60cfm fan. Some case fans for basic breathing. Thermaltake waterblock (kind of basic one) and 3/8 tubing for the loop. Pump is a swiftec mcp35x with small resevoir, all of this in a single loop.


My house temp is about 70-80F depending on the day.

Thanks again.

well yes, any more radiator will help. A 360 with fans (at least in pull if not push/pull) should make quite a difference (especially outside the case where it'll be in ambient temp. At 80F/27C you should be getting much better temps (approx low to mid 30's) and 60s during load with a moderate OC. You definitely need to make sure you're getting good flow through your waterblock (a RASA universal would probably do you some good. They are making them much more efficiently in terms of flow and heat transport) as well as the rads. Otherwise you loops looks fine.
