Anyone using a Thermaltake 745

Ive just ordered a 745 , and was wondering if anyone is using this setup. Im a noob to water ,and decided to go with a kit . To me it looks like it would take a gpu block without any problems. Compaired to a regular big water , the pump seems good 400/lph and the dual radatior setup seems enought to run a gpu /cpublock . Any comments /suggestions? thx for a great fourm . Rukkee

Seems like a heck of a deal to me. Pricegrabber shows it for $170. Google for reviews--the one I saw was very positive.

Not a good solution for those who want tweak-unique, but a simple way to get components that work together.

Hope this helps--stay cool.

I'm listening, I just have different preferences. Please forgive me for my nonconformity--I may need your help later.

For those who want an inexpensive, quiet, compact, turn-key system, the Bigwater SE and BigWater 475 have gotten very good reviews.

To wit:


I'm not saying it's the best for everyone, just offering another option.

Rukkee--I'm currently installing a BigWater SE in a P180 case. So far it seems pretty straightforward, and I don't have any tips other than the general ones for most systems--I suggest you look at the ***s in the stickies about installation, location, etc. I'll let you know if I learn anything, and feel free to PM me if you have any questions.

Stay cool!

Okay, you have me intrigued.

What would you spec for $153 or less complete, including tax and delivery, that would:

1. Have both CPU and GPU waterblocks (Athlon64 x2 and 7800 GT).

2. Easily mount internally in an Antec P180 case.

3. Have a silent pump--so quiet that you have to put your ear against it to hear it running. (This means either a silent high-flow pump or--if going with a silent low-flow pump--radiator & waterblocks that are optimized for low flow operation, unlike the high-flow units that custom folks usually use.)

4. Run with inaudible fans--say a 12cm fan at 1700 rpm.

5. Cool a 3GHz Pentium to below 37C under load.

Thanks for your offer--you could help out the silent-PC crowd.

RAD: 1986 Chevy Chevette Heater Core $18 from auto parts store.

Fan shroud: $2 Tupperware

From jab-tech.com:
Fan: Yate-Loon (under volted if you must have silence) $5.95

Tubing: Master Kleer 10ft $4.90

Fillport: Danger Den Fillport $11.95

CPU: Swiftech Apogee $40 with coupon code.

Comes to $71.03 shipped

Pump: Hydor L35 45.99 + shipping (I'm figuring $8)

Water: $1

Water add: $3

T fitting: $2


Sure a MAZE4 is going to cost you $45 more, but considering the fact that the average price tag on the normal Bigwater SE is $129.99 + 29.99 (the average price on the VGA block), I think that if I was given the time to wait for sales as you had, the price would be lower and I'd bet that I could add a waterblock to that for the same price. As an example, I got my Eheim 1250 pump for $32 shipped from ebay. So I think that making a decent custom setup for about $150 is possible.

If that pump wouldn't work for you, take a look at the swiftech MCP350. Transonic had a FAQ on how to increase the flow of it. It is more expensive then the BW pump, but guess what? It doesn’t fail and it works ALOT better.

Hey Snerp,

Thanks for the detailed recommendation--I'm sure it it a good example of an entry-level custom rig, and provides a basis for comparing a good basic kit with a good basic custom rig.

My comparison kit system, based on reviews, is the Thermaltake Bigwater SE, and Thermaltake Aquarius CL-W0038 GPU waterblock. These are available for $115 + $38 from ZipZoomFly, for a total of $153 delivered for CPU and GPU cooling, versus $151 for your custom system with GPU cooling alone.

Also, I doubt that nice big car heater core you're using will fit internally in most cases' stock fan locations without some modding. And I doubt that high-flow pump of yours is silent--my understanding is that one has to pay about $100 for a super-quiet high flow pump.

As I have all along, I concede that a custom system like yours offers superior cooling, and is the best choice for hard-core overclockers (that bigger radiator alone has got to be a big advantage). However, this comparision shows that a custom system isn't necessarily superior in all aspects.

Here are the relative advantages, as I see them:

Snerp's Entry-Level Custom Rig:

Superior cooling--ideal for extreme overclockers
Custom--user has many more choices
Satisfaction and accomplishment of a unique and personal build.
Educational--builder will learn more with a custom kit

DrDeville's Entry-Level Kit:

Excellent cooling--great for stock speeds, and mild overclocking
Compact--fits internally in most mid towers.
Cheaper--$153 for CPU and GPU waterblocks, versus $151 for GPU only.
Easier--only two things to order, and comes with instructions for the specific components.
Quieter--pump and fans are near inaudible--hard to hear over a quiet hard drive.

My point is that both alternatives have something to offer and, despite prevailing prejudice, a good basic kit has some advantages over a good basic custom rig.

Thanks for taking the time Snerp--I hope prospective buyers find our efforts useful.
