Core 2 Duo, GIGABYTE GA-P35-DS3R and cooling

Schlotkins · Post by **Schlotkins** » Thu Nov 22, 2007 6:18 am

I'm going with probably a E6750 and a GIGABYTE GA-P35-DS3R. I'm looking to get a heatsink I can use a 120mm fan on @ 5V. This board will be mounted vertically so I don't know if weight would be an issue on the bigger heatsinks.

Any suggestions are appreciated!
Chris

Good board and chip. I think the Scythe SCNJ 1100P will be your best bet if you plan to undervolt your fan to 5v. http://www.newegg.com/Product/Product.a ... 6835185038

Its not the best cooler, but I dont think Thermalright's Ultra-120 Extreme (best air cooler that I know) has enough space between its fins to allow air at such low pressure that you will have.

In any case, both coolers are pretty big, so make sure you've got room, both on the motherboard and your case width.

Would these be OK in a P180b and P150 case?

It looks like the extreme would be fine in the p180b... how about the p150?

Thanks,
Chris

I`ve seen users in this forum using those coolers on both mentioned cases with success. I would lean on the skythe ninja as it can work with low airflow, only concern is the mediocre mounting system.

Get something that won't use the pushpins, and you should be fine for the weight. The Ninja can work with TR's bolt-through, but is a PITA to install, due to having so little room, with the Ninja's fins in the way and all.

So people seem to be going with the Ninja, which is here right?

I thought the extreme was better (even according to the SR review), but hey, the Ninja is also 1/2 the price.

Thanks,

The Thermalright hasn't proven itself to be a great fanless cooler. I also would not trust anything that tall to the Intel pushpins. Even with low airflow, though, Thermalright's should best the Ninja, with a fan right there on it.

Yep, thats the one. I have the Ninja in my P180 case, mounted on a 775 socket mobo (Asus P5WD2). It wasnt hard to install for me. I dont mean to cast doubt on other people's opinions, its just that to my knowledge, socket 775 heatsinks have standard mounting holes. So to upgrade, yes its a pain in the butt, since you'd need to take the mobo out, but as a new system build, its not bad at all.

As far as your decision with the heatsinks; again, for low airflow, go with the Ninja. Thermalright is a better cooler (more heatpipes, more fins to distribute heat) but only with high airflow (more air pressure required to pass air through the small space between its fins, more pressure required = faster fan speed = noise).

Thanks for the all the help. I'll go with the ninja. Now, what fan to use? Should I go with the Scynthe mid speed fan and undervolt to 7V or something like that? I could also just go with the low speed fan at the full 12V.

Thanks,
Chris

I have a 500 RPM Slipstream cooling my Ultra-120 Extreme and E6750. It doesn't push that much air, but it is enough to keep my temps low. If you don't want to deal with undervolting fans, I think they are the way to go. The only downside is that it is a 3-pin.

Schlotkins · Post by **Schlotkins** » Sun Dec 02, 2007 6:35 pm

What's the downside of the 3 pin connector?

I assume either the ninja or the Ultra from newegg comes with everything I need right? I don't need to order any adaptors right?

Thanks!

I wouldn't worry about 3-pin voltage controlled fans vs PWM fans. Your motherboard can control either one fine.

Are you going to let the motherboard control the fan or use a separate fan controller?

I have to say that the most convenient thing for me was to use a 1000-1200 RPM fan and let the motherboard control it. By default, it seems to downvolt it to around 700-800 RPM and effectively never spins it up any higher.

I have a Thermalright Ultra-120 Extreme and am using a Scythe S-FLEX E fan - 3 pin motherboard controlled. As I found out, everything is fine with using a 3-pin fan into the standard CPU fan connector on my Gigabyte motherboard. I have the GA-P35C-DS3R but I'm pretty sure there aren't any mentionable differences for our discussion.

Oh, I'm cooling a Q6600 overclocked to 3 ghz.

I was just going to let the motherboard control the fan...

Bump... does the ninja linked above at Newegg come with everything I need for mounting on a 775 socket?

Thanks,
Chris

Just a little correction...

The TRUE will work just fine with a 120mm at 300-400rpm, even though the fin spacings are tight, it will be enough airflow to evacuate the heat.

An example (my setup):

Antec P182, P5W DHD mobo, E6600 @ 3.2GHz / 1.4V, Nexus 120mm on the cpu, Nexus rear exhaust and Scythe top exhaust, Nexus and Scythe intake (Kama bay).

That setup gives me about 38-40 degrees on the cpu at full load with all fans at 100%, and 56-58C on the cpu with exhaust fans at 350-400rpm, intake at 500rpm, and cpu fan at between 400 and 600rpm.

Yes.

OK I went with the Ninja and a 500rpm fan. After 4 hours of burning in, core temp (the correct version so there's no 15c problem) is reporting about 58c on two different builds. (One in a p180 and one in a Antec solo). Room temp is about 72f and these machines are going into A/C homes so it shouldn't rise by much in the summer. Is this OK? I'm not sure if 72C is the limit or 100C when looking at the temps through core temp.

I could upgrade the fan if that's not enough...

Oh, and the CPU is a 6750 on a Gigabyte DSR board.

Thanks,
Chris

If you want even better northbridge cooling, the HR-05 and the Ultra-120 Extreme will fit on a DS3R. I have the DS3L version but the layout is almost the same. Just that mounting the fan clip on the HR-05 side requires a lot of patience.

Here's my setup:
